对“置换法测定金属的当量”实验的改进

Improvement on Experiment of Determining Metal's Equivalent weight

本文从原理上对该实验进行了部分改进,用“原子量”取代了“当量”,并建议将实验题目改为“置换法测定金属的原子量”。克服了实验教学中的疑难问题,有利于更好地达到实验目的。

The article makes partial improvmcnt on the experiment of permutation determination of metals equ alent weight in theorem and replaces' equivalent weoght' with 'atomic weight' with the suggestion that the experiment name be changed into 'per mutation determination of metal's atomic weight'.
