Abstract:

Conservation law is widespread in nature. Analytical chemistry is often related to many conservation laws, such as material conservation, charge conservation, proton conservation, electron conservation, etc. In analytical chemistry, conservation laws can be used to derive many formulas and to solve some complex calculation problems. In long-term teaching practice, the writers find that conservation laws can help students to understand many formulas, simplify the complicated process, consider the problem on an overall perspective, and not to consider trivial details.

Key words: Analytical chemistry, Material conservation, Charge conservation, Proton conservation, Electron conservation
