间接碘量法测定高锰酸钾溶液的浓度

Indirect Iodometric Method for Determining the Concentration of Potassium Permanganate Solution

采用稍少量的KMnO4进行溶液配制,探讨了间接碘量法标定KMnO4溶液浓度的原理和方法。此方法比Na2C2O4标定法操作简便,节约近半时间,结果较准确。

Using a small amount of KMnO4 to prepare the solution,principles and method of indirect iodometric calibration of the KMnO4 concentration are discussed.This method is simpler compared with Na2C2O4 calibration,and saves nearly half the time,the results are more accurate.
