本文介绍了在110±5℃、270±10℃、600±10℃处理的基准级氯化钠标定0.1mol/L硝酸银溶液的结果,分别用荧光黄作指示剂,指示终点。结果显示,使用在不同温度下处理过的氯化钠所标定的硝酸银溶液的浓度无显著性差异。
In this paper, the results of calibrating 0.1 mol / L silver nitrate solution with reference grade sodium chloride treated at 110 ± 5 ℃, 270 ± 10 ℃ and 600 ± 10 ℃ were respectively indicated with fluorescent yellow as indicator to indicate the end point. The results showed no significant differences in the concentrations of silver nitrate solutions calibrated with sodium chloride treated at different temperatures.
