莫尔法测定水中氯离子终点误差校正

Correction of the End-point Error in the Determination of Chlorion in Water by the Mohr Method

莫尔法测定水中氯离子，硝酸银作标准溶液、铬酸钾作指示剂，采用终点等体积纯水做空白实验校正终点误差。该法应用简便、分析结果可靠。

The Mohr method is used for the determination of chlorion in water with silvernitrate as standard solution and potassium chromate as indicator. The end-point error is correctedby blank test with pure water the volumn of which is equal to that of the sample at the end point.This process is easy to operate and the analytical results are riliable.
