A Formula-Free System for the Course of Analytical Chemistry

Analytical chemistry (the part of quantitative chemical analysis) is an important course in many universities. The traditional system of the course can be characterized by “calculation through memorization” and “simplification through approximation”. A large number of formulae not only result in heavy burden of memorization, but also tear the uniformity of the theory of chemical equilibrium. In order to solve such problems, a new formula-free system is designed. The new system features low demand on memorization and high level of uniformity, and makes accurate calculations possible. The details of the new system are presented in five aspects including background, characteristics, resources, examination and practices.
