| 摘 要： | 讨论了酸碱电位滴定中，只需测定两次滴定剂体积与相应的溶液ｐＨ值、利用公式确定滴定终点、计算被测酸碱含量的方法，并对方法的可行性及准确度进行了研究。本法与指示剂法相比，相对误差不大于０．２％，标准样品回收率达９９．７９％～１００．２％。

| Abstract: | The double-point acid-base potentiometric method is described here. It is only in twice based on the pH indicating and its corresponding volume of the standard solution in the acid-base titration. The end-point of titration can be calculated by a simple formula. Comparing with the indicator method,the relative error is less than 0. 2%,and the rate of recovery is in range of 99. 79% -100. 2%. |
