摘要
高锰酸钾溶液广泛应用于氧化还原滴定法中。但高锰酸钾的试剂常含有少量杂质,使溶液不够稳定,而且KMnO_4氧化能力强,可以和很多还原性物质发生作用,所以干扰也比较严重。为此,对KMnO_4标准溶液的配制与标定要控制好条件,否则影响实验结果。
Potassium Permanganate solution is widely used in redox titration. But Potassium Permanganate＇s reagent often contains a small amount of impurities, the solution is not stable, and KMnO4 oxidation ability, and many reductive substances interact, so interference is more serious. Therefore, the condition of preparation and calibration of KMnO4 standard solution should be well controlled; otherwise the experimental result will be affected.
