Abstract

Students have a greater appreciation of the principles of chemistry if they can see the relevance to their lives. Calcium supplements provide an excellent context in which to review most of the core content of general chemistry, namely, stoichiometry, concentration units, hydration of salts, inorganic and organic salts, physiological importance of elements, resonance in ions, geometry of polyatomic ions, and isomerism. A set of questions covering the cited topics and the corresponding answers are presented to encourage the critical thinking by students.
