四、氧化还原滴定法1、概述氧化还原滴定法是以氧化还原反应为基础的滴定方法。它有以下几个特点:(1)标准滴定溶液的种类多较常用的标准滴定溶液有:a、碘量法氧化剂有碘、溴、碘酸钾等际准滴定溶液。还原剂有硫代硫酸钠等标准滴定溶液。b、高锰酸钾法氧化剂有高锰酸钾标准滴定溶液。还原剂有硫酸亚铁、草酸标准滴定溶 Fourth, redox titration 1, an overview Redox titration is based on the redox reaction titration method. It has the following characteristics: (1) the standard titration solution more commonly used standard titration solution: a, iodine method oxidant iodine, bromine, potassium iodate and other international quasi-titration solution. Reducing agent sodium thiosulfate and other standard titration solution. b, potassium permanganate oxidant potassium permanganate standard titration solution. Reducing agent ferrous sulfate, oxalic acid standard titration solution
