摘　　要：溶液的酸度、水质、空气及光照等因素对高锰酸钾标准溶液的稳定性及滴定反应有较大影响 ,而条件及人为因素对标定高锰酸钾标准溶液的准确度影响也很大。结果表明 ,在消除各影响因素下配制的高锰酸钾标准溶液 ,室温下完全可以保存 2个月 ,浓度基本不变。Factors such as the solution acidity,water quality,air and light have great influences on the stability and titration reaction of the standard potassium permanganate solution,so do the conditions and artificial factors on the accuracy of its calibration.The results indicate that the standard potassium permanganate solution prepared can basically sustain its concentration at room temperature for two months,with various influencing factors eliminated.
