摘　　要：采用电位滴定方法测得一组极弱酸的Ｖ－ｐＨ值，经最小二乘法处理及计算机编程计算，即可求得极弱酸的滴定终点Ｖｅ和离解常数Ｋａ。The poten tion metric titrate by computer data processing for determining titrating endpoint and dissociation constant of extremely weak acid is presented. The linear titration equation,y=Ve-k·x, is derived. The Ve and Ka(Ka=1/K)of extremely weak acid by this methodare given and the results are satisfactorv.
