A total of 122 high-school students (15–16 years old) were involved in the study and a solubility concept test was administered in order to get insight into their conceptual knowledge. S...

As is well-known, the chemical knowledge is acquired at three levels: the macroscopic and tangible (what can be seen, touched and/or smelt); the sub-microscopic (atoms, molecules, ions and structures) and the representational (symbols, formulae, equations, mathematical manipulation, graphs etc.). In order to acquire real knowledge, all factors invo...

The easy oxidation of the substances containing aldehyde groups using a mild oxidizing agents, such as solutions containing copper(II) or silver(I) ions, can provide a mean to detect the presence of carbohydrates known as reducing sugars. However, using such tests, it is not possible to distinguish between aldoses and ketoses because the alkaline c...

The purpose of the study was to investigate the ideas of students about some basic chemical concepts, such as dissolving, burning, structure of ionic substances, as well as reactions involving gases, external condition and limiting reagents. Also of interest was the way students understand and use symbolic representations in writing equations or re...

A study was conducted to identify concepts about the particulate nature of matter among secondary-and high-school students (N = 187) and to address some misconceptions regarding this topic, especially the misunderstandings related to the vague ideas of the relationship between the macro and micro world. Data were collected using both quantitative (...

The notion that acid salts exist only for diprotic and polyprotic acids is found in many high school and university textbooks, although the “only” condition is not always stated explicitly. A fairly simple experiment shows that there is a pronounced exothermic effect when pure acetic acid is added to potassium acetate. Experiments with similar react...

The process of sublimation is defined unequally in various chemistry sources. Its standard definition is, in a way, analogous to that for evaporation. However, there is no special term for the sublimation equivalent to boiling! Being so, one should perhaps not be surprised that a number of misconceptions related to sublimation, (especially sublimat...

Sublimation is a process that is defined unequally in different textbooks and in various chemistry sources. Inexactness in defining basic concepts in chemistry can lead to alternative meanings for different people. Inconsistent explanations, then, can serve as a basis for developing misconceptions and preconceptions in latter students’ education...

The number of first-year students of chemistry in Macedonia is declining in the last few years. An informal group (both teaching staff and Ph. D. students) called The Happy Chemists Group initiated the organization of a series of evening events with spectacular experiments, hoping to 'infect' high-school students with 'the chemistry virus'. A demon...

This letter to the editor about a recently published article raises a question of how spectator ions should be most accurately defined.

A graduated cylinder filled with NO is placed under water. The water level in the cylinder slowly increases. The experiment has been performed earlier and was interpreted as a result of a steady transfer of oxygen from the air through the water, the NO being consumed in a chemical reaction with O2. The explanation, however, was based on a preconcep...

Metallic aluminium was found not to react with either concentrated or diluted nitric acid. Providing the diluted acid contains dissolved sodium chloride and traces of copper(II) cations, a vigorous reaction occurs. The product is basically nitrous oxide (possibly containing some elemental hydrogen and nitrogen gases), and was identified by its IR s...

During the last two decades, numerous attempts have been made to "modernize" science education, chemistry education in particular. Microscale experiments, such as projected experiments, have become favorites of many educators and instructors. Although these experiments might be useful for hands-on approach or for quick demonstrations in large lectu...

span>Upon pressing small pieces of sodium and potassium with a glass rod, the solid pieces turn into silvery liquid product — a K–Na alloy. The alloy reacts with water very vigorously (often an explosion occurs). This experiment is reserved only for chemistry instructors, providing they take all necessary precautions. Two much safer experiments are...

Continuous thermochromism was studied in systems containing metal chlorides and diluted hydrochloric acid. Most of the divalent and trivalent transition metal chlorides were included. The color changes may vary from barely visible (e.g. in MnCl2-HCl-H2O), through visible (e.g. in NiCl2-HCl-H2O) to remarkable (e.g. in MoCl 3-HCl-H2O). Well known exa...

The precipitates formed upon the action of aqueous solution of potassium iodide on aqueous solutions of lead(II) nitrate and lead(II) acetate, respectively, are different. The assumption that in the presence of acetate a double salt Pb(CH 3 COO)I has been formed, was ruled-out by IR spectroscopy. Some simple additional experiments prove that the pr...

Chemical equilibrium is characteristic in all cases where the direct and the reverse reaction occur simultaneously. The equilibrium reagent composition can be altered by changing the pressure, the temperature or the concentration of some participants in the reaction. In this paper a lecture demonstration is offered showing the temperature dependent...

Laser pointers enable the instructor to make the old demonstrations more attractive and more vivid. Examples are offered for demonstrations of optical properties of heterogeneous systems (suspension, emulsion, colloid, smoke, fog etc.), where the light scattering on the dispersed particles reveals the non-homogeneity of the system. Two more remarka...
