摘要
溶液的酸度、水质、空气及光照等因素对硝酸银标准溶液的滴定反应及稳定性产生影响,而条件误差、人为误差对标定硝酸银标准溶液准确度的影响也很大。实验证明,在消除以上各因素条件下,配制与标定的硝酸银标准溶液,在室温下可以保存2个月浓度基本不会改变。
The acidity of solution,water quality,air and sunlight affected the titration reaction and stability of the silver nitrate standard solution,and the effect of condition error and human error on calibration accuracy of silver nitrate standard solution was also great. The result showed that the silver nitrate standard solution prepared and calibrated by eliminating all factors mentioned above can be stored at room temperature for 2 months,and the concentration would not change.
