I am working on a chemistry lab report that revolves around the relationship between coagulant dose and its effectiveness at coagulating orthophosphates in lake water.
One of my theoretical questions is as follows:
Calculate the dose of coagulant in mg·L -1 , if the alkalinity of the water before treatment was 5 mval·L-1 , and its acidity was 0.4 mval·L-1 , and the pH of the treated water after coagulation with AlCl3 must be neutral (pH 7).
Thanks!
while drill in some reservoir observed detected helium and Co2 , could we figure out the environment from this geochmical fingerprint. or we can understand the paleo- climate in these reservoir.

Hello everybody
I want to simulate MXene by means of molecular dynamics method. But it seems that I need the Mxene atomic structure as a file in .cif, .pdb, or .mol format.
Is it possible for anyone to tell me how I can get the files or how I can build the atomic structure of MXene?
Thank you so much
I need to make 3 solutions of 5, 10, and 20 wt% of Co(NO3)2 but I'm not sure how many grams I should take for each solution. Can anyone help me?
I am aiming to keep the humidity more or less stable in a closed chamber.
Therefore I am using a saturated salt solution in a closed chamber for that experiment.
What bugs me is, that I always end up with salts growing up on the inner faces of the vessel where I put the solution in.
The salt is, btw, growing even above the initial fill level. So the evaporation seems no to be the only reason. I guess this is related somehow to the capillary effect?
Is there a way to easily prevent this
Different authors prefer different terminologies to indicate the forms of trace elements present in the soil. Hooda (2010) in Trace elements in soils used trace element fractions. Kabata-Pendias (2010) in Trace elements in soils and plants used trace element species. Basta et al., (2005) in Trace element chemistry in residual-treated soil: key concepts and metal bioavailability used trace element pools.
Is the reaction of Anthocyanin to pH reversible? I mean if we increase the pH and get the color change, if we then decrease the pH, the color will be changed back to its original color?

Hi all, let me introduce my self. My name is Aini. I got my bachelor degree in chemistry education major so my research related to educational field. I don't think I enjoyed to do research in educational field. So in short, I decided to continue my study in Chemistry Department. It was a tough years to finish my master degree but I like the research. I like the research because the results are very real, measurable, having high level of validation and accuracy. But because my bachelor degree is not relate with my master degree, I have no confidence to continue my study to doctoral degree. I really want (and also have to) continue my study but I thought that I must have a certain field about my research, while I am not expert in any certain field (since I do different research at bachelor and master degree). Now I really got confusion in making my proposal for the doctoral degree and still not sure what topic (in chemistry not in educational field) I should take. Can anyone please give me advice how to start finding a topic or start making a proposal for doctoral degree with my condition? I am looking forward for your replies. Thank you
Hello All! I am working on a project that uses stable isotope analysis (C and N) to look at the diets of California reef fishes. I am going to be collecting Liver and White muscle tissue. It was suggested to me to use 20ml borosilicate glass scintillation vials (urea caps with polyurethane lined caps/not foil lined) for my tissues. I will be freezing the tissue samples in the vials and drying them in a 65C drying oven in them as well. The issue I am running into is that every brand of vials are back ordered for about 4 months no matter where I look.
So I wanted to see if 1. Anyone in the southern California/greater LA Area had vials I could buy off of them to use. Or 2. If anyone knew of a substitute I could use. It has been suggested that I could hand make aluminum foil packets, pre combust them, and store/dry the tissue in those. However, I would prefer the glass vials for both, organization/storage sake as well as I will eventual be grinding the powder into a powder and vials would be less likely to fail with the powder.
Thank you in advance for any advice!
I'm working on a project with this topic and this is my first time and I don't know how to go about it
Hello!
Ive been trying to use the ninhydrin assay to measure concentration of PEIMax accurately after dilution. PEIMax is deacetylated 22kDa linear PEI*HCl so it should only contain secondary amines and should supposedly only form yellow compounds that absorb at 440nm with ninhydrin reagent. When I run the ninhydrin assay with PEI however, i see an obvious purple color and i can make wonderfully reproducible and linear standard curves using either 440nm or 570nm absorbance. I am using the Sigma 2% ninhydrin + hydrindantin in pH5.2 LiAc, reacting at 80C for 10 min in a PCR plate sealed with nitrogen blanket (https://www.sigmaaldrich.com/US/en/product/sigma/n7285).
Anyone have any ideas as to why I might be seeing such strong absorbance at 570nm even though i dont have any primary amines in the sample to form Rheumann's purple?
Another point I suppose that might be worth mentioning is I reconstitute my PEImax in 0.1M HCl however Ive run HCl alone in the assay and not seen any color change.
Thanks in advance!
SNAP
How to use SNAP as a nitric oxide donor correctly? Is it possible to prepare a stock solution and store it in a freezer, and prepare the working concentration by dilution before application?
Or should SNAP crystals be dissolved immediately before use?
Hi,
Anyone know of any bases with boiling points < 100C that I can pretty easily boil off after a reaction? the lower the better and cannot contain any amines so ammonia is out

Hi everybody: i need your help to solve this issue about chemical equilibrium calculation
On this case my available datas are
Volume: 1 L
Temp: 25°C
Reaction (already balanced) --> N2 (g) + 3 H2 (g) <--> 2 NH3 (g)
Moles of reagents and products (at equilibrium condition)
N2= 1 mol
H2 = 1,5 mol
NH3 = 1,8 mol
I need to:
- calculate equilibrium constant
- set up a new equilibrium equation (no need to solve) to determine new composition when 0,5 mol of NH3 are removed from the container
Basically i am stucked in a certain point and i can't go any further. I'd be really grateful to everyone who will reply and also will have the patience to explain step by step the method applied
Thanks a lot
Hello. I received a compound with molecular weight 453.292 and the only mass information for it is 1 micromol. This is very confusing because usually chemicals have a mass in grams or milligrams. I do not know how to calculate from this. I need to make up either 10mM or 1mM of the compound. Please can someone show me your calculation for either obtaining a final concentration of 10mM or 1mM (please show calculations for both, as i havent decided which one to make yet), how much DMSO I will need to use. Thank you

Im thinking about trying to synthesize some poly beta amino esters, however Im not sure if the chemistry is air sensitive or just water sensitive. The reaction is a polymerization reaction between amines and acrylates via Michael addition.
Also was wondering if you are supposed to remove the inhibitors from the monomers using inhibitor removal resin or keep them in, the materials and methods sections of these PBAE synthesis papers dont mention it, but it seems like something that would be necessary.
Hi there,
I've been noticing that after adding my blocking chemicals (TEA-Cl and CdCl2) to isolate sodium current, my pH increases beyond my ideal point (I'm trying to stick around 7.4 and it drifts to around 8.0 after adding both) and there is first cloudyness and then precipitate forming in the solution after addition of the CdCl2.
Prior to adding the blockers, I am bubbling my ACSF with carbogen for twenty minutes. I also do not add sodium bicarbonate or dextrose to my 10X stock. My concentrations for ACSF (working solution) are as follows:
125mM NaCl
2.5mM KCl
1.25mM NaH2PO4
1mM MgCl2
25mM NaHCO3
25mM dextrose
2mM CaCl2
75mM TEA-Cl
0.2mM CdCl2
Again, target pH is 7.4. Would really like some input on this, as well any any relevant chemistry as to what is happening. Thank you!

hi everyone.
Is there any accurate formula to find the diffusion coefficient of peptide and its ions (COO-) and (N+(CH3)3)?
My current work is producing a reasonable amount of dibenzyl ether contaminated with a small amount of dichloromethane, approximately 10% vol. I would rather reuse the reagent than throw it away, so can anyone recommend a simple method for extracting the dichloromethane.
Dear James,
thanks for posting this interesting technical question. As already mentioned by Salim, the boiling points of dichloromethane and dibenzylether are far apart so that a separation by distillation is easily possible. However, I would not recommend to use a rotary evaporator. This way you can easily remove the low-boiling dichlormethane, but high boiling impurities and decomposition products will remain in the dibenzyl ether. Thus I would recommend to use a classical distillation apparatus as shown in the attached picture which was taken from the very instructive Wikipedia entry on the term "Distillation". First you can distill off the dichloromethane under normal pressure. Then replace the receiving flask and distill the dibenzyl ether under vacuum (oil pump etc.). This will give you a pure product. I'm pretty sure that some brownish residue will stay behind... 😎
Good luck with your work and best wishes, Frank Edelmann
I need to make the following HEPES buffer:
"Dissolve 1.6g NaCl, 0.074g KCl, 0.027g Na2HPO4.2H2O, 0.2g dextran (glucan or dextran) and 1g HEPES in 90ml of distilled water, ..."
The buffer is for plant leaf infiltration.
The instruction don't specify what MW dextran/glucan to use and dextran/glucan are really uncommon chemicals to have around. Is there anything comparable biochemically I can substitute for them? Maybe polyethylene glycol (PEG) or Ficoll?
Additionally, would using dextran sulfate be suitable to using dextran or would there be undesirable effects from the sulfates?
I am trying to imagine a problem where particles in water climb/coat onto an air bubble in bulk water. Is this even possible?
If yes, if we form equations, will that have the same surface tension as water-air (say 25 C) along with a force balance?
To complement this: Yes, using solid bubbles (say beads of glass) or simply a glass slide, we can make the water stick to it using surface tension
Your inputs are much appreciated! Thanks:)
The Chemistry of reaction and detailed mechanism leading to the formation of the green nanoparticle would be greatly appreciated.
Hi there,
It is clear that we use many types of hydrophilic additives containing hydroxyl groups in the PES dope solutions to provide a less hydrophobic membrane.
Is there any physical interaction between the sulfone group of PES polymer chains and hydroxyl groups of hydrophilic additives in the membrane matrix?

In Becke's B3LYP hybrid functional, Fock exchange is being mixed with Slater LSDA exchange (and then plus gradient correction), plus correlation expressions. But what LSDA exchange parametrization is used?
- It appears to me that Becke in his DFT Thermochemistry I paper (J. Chem. Phys. 96, 2155 (1992)) uses the VWN parametrization, being the then modern alternative to the older Perdew-Zunger version.
- Then in his Half-and-Half paper (J. Chem. Phys. 98, 1372 (1993)), he apparently switches to the then recent Perdew-Wang 1992 parametrization.
- In his 3-parameter hybrid (DFT Thermochem III) paper (J. Chem. Phys. 98, 5648 (1993)) he seems to only comment on correlation being taken from the PW 1992 parametrization and not mention which LSDA version he uses for the exchange part, presumabely still the standard Slater exchange (E_X ~ int n_(alpha)^(4/3) + n_(beta)^(4/3) dr.
So which LSDA parametrization is used nowadays in B3LYP? Did people stick to the VWN version from Becke's initial paper or did they switch to the more modern PW version as Becke probably did? Or do different implementations in program packages use different versions?
Hello. Thank you for paying attention.
What is the typical values of excess air in natural gas power plants? Is 100% excess air an appropriate value for natural gas (methane) ? When I modeled the power plant the time I set excess air about 100% true range for the turbine inlet air temperature was obtained (around 1300-1400 K).
So I was running an IR on a sample that I had thought (or rather hoped) was phenol (hydroxy benzene), but what came out was either trash and noise, or I simply did not have phenol. My professor and I were quite stunned as it showed no signs of organic peaks at all, especially no -OH peak near 3100. My professor suggested to run my reaction again, but sadly I do not have the reagents on hand at the moment and it will be some time before I get them.
The reaction I ran was one taken from an old book on recycling benzene waste. When I conducted it, I took a mixture of nitrobenzene and benzene waste and I added a random amount of relatively pure Fe2O3 and 13% Hydrogen Peroxide to try and oxidize anything in the waste to phenol or hydroxynitrobenzene. After I treated it with NaOH to make a phenoxide salt and then I did some work up to isolate. What I was left with was a nice white crystalline salt (or so I thought). But the IR says it contains zero organics as far as our IR machine can tell, and our machine is used daily if not hourly, and is kept in great condition.
If someone could help me understand what I have or teach/lead me how to identify inorganics, that would be very appreciated.
Because the attached picture is possibly hard to see small details, I have listed the peaks as well.
Peaks:
-610.07 cm^-1 transmittance: 60%
-635.08 cm^-1 transmittance: 79%
-1091.13 cm^-1 transmittance: 64/65%
Rizal Awaludin Malik After rereading my notes, I have come to realize that I distinctly changed my procedure because I was having trouble with the Iron Oxides previously mentioned. My pseudo-procedure looks more like this:
Fe + 2HCl -> FeCl2 + H2
2FeCl2 + Cl2 -> 2FeCl3
FeCl3 + H2O2 (13% aq) -> Fe(OH)3 + Reactive Species
And my idea was to combine the benzene/nitrobenzene wastes I had with the final reaction in the scheme (combining the reactive species) to try and produce hydroxylated benzene and nitrobenzene.
Some notes from my notebook leave me further puzzled:
"Smell of nitrobenzene and benzene has totally disappeared, and lots of gas evolution. A red precipitate (likely iron oxides) has formed at the bottom of the beaker. There is no longer 2 layers (2 phases) and the yellow color of the solution is very faint, where it was quite deeply colored beforehand."
I'm not sure what exactly happened but I have done a little bit of searching and came across Hexaaqua iron (III) chloride, which may be what I have crystallized out.
To explain further, after the whole reaction was completed, I filtered off the red precipitate and tried to crystallize out whatever product I had formed. When I did so, I was left with a pure white free-flowing powder. The powder seems hygroscopic in nature.
I will likely try this again, with pure benzene to see if the same result occurs.
We are interested to establish a Chemistry Research Institute/Department here at Sukkur Institute of Business Administration University (SIBAU), Sukkur, Sindh, Pakistan. Suggestions and Guidance will be highly appreciated.
There were five pretests administered to both groups. Each pretest represents a different topic in chemistry (Matter and Its Interaction). In lesson 1, the experimental group has significantly higher group means than the controlled group. In lesson 2, two groups have statistically equal group means. In lesson 3 and 4, the control group has significantly higher group means than the experimental group. In lesson 5, the two groups have statistically equal group means. In the overall pre-summative test, the two groups have statistically equal group means.
Dear science community!
I need your help, please!
I`m totally disapointed and at a loss!
In 2020 (at the end of October) there were the IOP Conference Series: Materials Science and Engineering (ICoSiET 2020). Me and my colegues took part in these conference. As the result (like a result of any other conference) the thesis collection should have been published (at the 4th quarter of the 2020)). Unfortanately, these collection still haven`t publised (despite the fact that 2021 is already at its end).
So, I wonder, if there are anybody, who know something about this situation? Maby there are any of those who also waiting for their thesis?
We have wrote lots of messages to the organizators and the head of the university (in which this conference took place) but they stoped to respond us.
I think this situation shows disrespect for the conference participants. And I believe that such situations should be inlighted in our community!
Thank you, for your attention!

HI All,
I'm doing a survey as part of an Audacious program (https://www.startupdunedin.nz/audacious), which essentially is a StartUp initiative at Otago University. I'm curious to understand what level of programming do biologists these days need during their day to day research.
For all the biologists out there here are some questions to start the discussion on this topic:
1) Have you done any programming till date? If so which language did you use and for what purpose?
2) How have to overcome programming limitations? For example, did you get the work done through bioinformaticians, or sought help from your programming friend, etc?
3) Have you used online biological databases for your research? If so, which one?
4) How much of artificial intelligence have you used in your research? Do you see AI potential in your current work?
If you have anything else to add, please feel free.
I extracted the essential oil and I found that my major compound represent 95 % of the mixture and only less than 5 % as minor constituents ( 20 constituents).
I'm I allowed to take my major constituent as starting material to perform chemical reactions?
Do the minor constituents representing only 5 % will not disturb the obtention of the desired compound?
I would like to insert some functional groups to increase bioactivity.
Any help in this regard will be appreciated.
What kind of functional groups do we need to insert by the synthesis in organic chemistry to have anti-cancer activity in perspective?
A performance task? A standardized test? Or some other means? Why?
I want to start from phenol to synthesize this compound, but I dont know about the detailed mechanisms and conditions.
Dear Jialiang,
many thanks for sharing this very interesting technical question with other RG members. I did a SciFinder search for this compound and found that it is not known from the previous chemical literature. However, the analogous compound is known in which the ethyl group in para-position of the phenyl ring on the left side is replaced by a methyl group. This compound has been reported in the following article:
Chemoselectivity in the Cu-catalyzed O-arylation of phenols and aliphatic alcohols
Fortunately this paper has been posted by the authors a public full text on RG. Thus you can freely download it as pdf file and print it out if required. The synthetic route is outlined in the attached reaction equation. You just need to replace the starting material 4-iodotoluene by 4-iodoethylbenzene.
Good luck with your reserach work and best wishes, Frank Edelmann

I need to know that after dissolved EDTA in suitable solvent e.g. water, isopropanol etc.. what are the ionic species will form and how to confirm those ionic species presence using which characterizations? any references regarding EDTA dissolving reaction chemistry will be helpful. Thank you.
I'd love to see a rough sketch of how the task would go.
I have read few articles (mostly based on simulations) that show metal nanoparticles bond with graphene or graphene oxide. However, I am thinking about how can metal (i.e. 0 oxidative state which is already in the lowest energy form chemical bonds with graphene (with no functional groups) or graphene oxide (has functional groups). I personally believe that metal nanoparticles are mostly adsorbed (Vanderwall forces) and no chemical bonding can occur. Please let me know your thoughts.

Hey
I need the free amine of Cystamine for my next reaction step but Cystamine is only available as a HCl salt.
i cant find any procedures/instructions on how to release the free base.
I tried dissolving it in 2M and 10M NaOH solution and extract it with chloroform and then evaporate the Chloroform on the rotavap – did not work
I also added NaCl to the aqu phase to saturate it – also didnt work.
anyone who worked with Cystamine or Cysteamine before and has a clue on how to Free the base?

I am looking for a software that can predict the chemical reactions that will occur when I mix certain substances. For Example: Na+Cl --> NaCl.
I was preparing a phosphate buffer and adjusting its pH to 7.2 from 9.0 by adding monobasic phosphate. In the beginning, it started to decrease fast but then, it went slowly (it was about pH=7.6). Even though I added too much monobasic solution, its pH was not increased easily. Then, it went to pH=7.3 easily but it stopped at pH=7.3 again. I wonder why it happened. I know it is related to its titration and the titration graph is fine to understand but I need a comprehensive explanation for it.
We have small molecules, measured the critical micellar concentration. we getting keep negative value. it is a bit surprising. if anyone can explain the reason with support of literature will be helpful for us to come over the issue.

Hello everyone,
I have a serious problem with coating the Pd/C catalyst uniformly on the glassy carbon.
I prepared the Pd/C ink by adding 20 mg of Pd/C into 9 mL of DI water. Then I sonicated it for 10 mins. I added 1 mL of IPA into the mixture and sonicated for another 10mins. I pipetted 5 uL of the ink on the center of glassy carbon (Diameter=3mm) and dried it in the air. To avoid any dusk from the air, I used a biker to cover the glass carbon. But I can't get a uniform layer of Pd/C catalyst on glassy carbon. Here is the picture of the Pd/C film. Can anyone help me with this problem?
Thanks,
Jay
