摘　　要：守恒是自然界普遍遵循的定律,在分析化学中也涉及到许多守恒定律,如物料守恒、电荷守恒、质子守恒、电子守恒等。在分析化学教学中,守恒定律不仅用于许多公式的推导,还能用来解决复杂的计算问题。笔者在长期的教学实践中发现运用守恒定律来解决问题,不仅能帮助学生了解公式的来龙去脉,还有助于帮助学生从宏观全局考虑问题,将复杂的过程简单化,而不必在过程细节上纠缠。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.

关 键 词：分析化学 物料守恒 电荷守恒 质子守恒 电子守恒
