[Co(NH3)6]Cl3的组成测定是基础化学实验中的一个综合实验,本文对Co2+和Cl-的测定方法进行了探讨。对Cl-的测定方法进行了改进,发现Co2+的测定用氧化还原法比配位滴定法更精确,Cl-的测定佛尔哈德法优于摩尔法。
The determination of the composition of [Co (NH3) 6] Cl3 is a comprehensive experiment in the basic chemical experiments. The determination methods of Co2 + and Cl- are discussed in this paper. Cl- determination of the method was improved and found Co2 + determination with redox method is more accurate than the coordination titration, Cl- Determination of the Faulhard method is better than the molar method.
