摘要
探讨了在沉淀电位滴定中只用两组E-V 数据,利用简单的公式便可以直接计算出滴定终点体积Ve 值.讨论了选取E-V 数据点组与相对误差的关系,对该法准确度进行了研究,相对误差小于0.09%.该法简便,快速准确,为计算沉淀电位滴定终点开辟了新的路径.
The method caculating precipitation potentiometric end point volume V(?)bya simple formula was described and only two groups of E—V data were needed.Therelation between data selection and error was discussed.The new caculating method isfast,simple and accurate.The relative error is less than 0.09%.
