Abstract

A method has been developed for the precise assay of potassium dichromate by constant-current coulometric titration with ferrous ions generated at a platinum cathode. It, is shown that one-half gram samples of the dichromate can be titrated with a standard deviation of 0.003 percent.

重铬酸钾的精确库仑滴定。
通过铂阴极产生的亚铁离子进行恒流库仑滴定,开发出了一种精确测定重铬酸钾的方法。实验表明,半克重铬酸钾样品的滴定标准偏差为 0.003%。
