摘　　要：依据Kohlrausch离子独立运动定律的基本原理,采用经典的电化学实验方法,测定强电解质溶液的无限稀释摩尔电导率,间接求出弱电解质溶液的无限稀释摩尔电导率。从而设计出一种测定弱电解质溶液无限稀释摩尔电导率的实验方法,应用于物理化学实验教学。该实验方法简便,结果准确。The limit conductivity of strong electrolyte solution was determined with classical electric chemical experiment method according to Kohlrausch＇s Law of Independence Migration of Ions, and indirectly the limit molar conductivity of weak electrolyte solution was calculated. An experimental method for determining the limit molar conductivity of weak electrolyte solution was set up, and it could be applied to the experimental teaching of physical chemistry. This method is simple and the result is precise.
