Abstract

This paper presents a set of motivating exercises to study various general chemistry topics such as formulation, molar mass, stoichiometry, chemical equations, balanced equations, oxidation states, acid–base reactions, tautomerism, calculation of formal charges, resonance, chlorinating agents, and the use of chlorine for disinfecting water. These topics can be studied in part through the information found on the labels of chloroisocyanurates, such as sodium dichloroisocyanurate (anhydrous and dihydrate) and trichloroisocyanuric acid, which are used for disinfecting water. Both compounds are readily available as consumer products. The holistic approach presented in this article allows students to focus on the versatility of the general chemistry concepts.
