摘要
讨论了间接碘量法标定高锰酸钾(KMnO4)溶液准确浓度的原理和方法,采用了比理论值稍多量的KMnO4配制溶液。间接碘量法与Na2C2O4法相比,不仅操作简便,反应时间短,而且测定结果准确度高。
To discuss the principles and methods of indirect iodometry method to demarcate concentration solution of KMnO4 using a little more than theoretical of KMnO4 for preparation of the solution. Compared with Na2C2O4 method,indirect iodometry method had easier operation,shorter reaction time and higher accuracy.
