摘要
在滴定法测定弱酸（包含多元弱酸）的浓度时，用ｐＨ计测得多元弱酸的酸度（ｐＨ值）和各个化学计量点的ｐＨ值，就能计算出多元弱酸的各级离解常数（Ｋ）．按此法得出的离解常数Ｋ值与文献值比较，相对误差在５％以下。
The method of measuring the dissociation constant of weak acid and poly-acid is researched through experiments. The data obtained from the experiments are compared with the literature values. It is found thatthe data coincide fairly with the literature values.
