介绍了用电位法的酸碱滴定来测定等当点的数学处理方法。这个方法的优点是利用线性滴定法来代替传统的滴定曲线。文中导出了公式,并介绍了计算步骤。当酸的稳定常数在10~7～10~(11)范围时,这些公式有可能比较准确的来确定等当点。同时,对强度接近相等的酸的混合物,也能得出满意的结果,即也有可能测定稳定常数相差仅0.5单位的两种酸,其误差小于1%。
Introduced the potential method of acid-base titration to determine the equivalent point of the mathematical approach. The advantage of this method is the use of linear titration instead of the traditional titration curve. The paper derived the formula, and introduced the calculation steps. When the acid stability constant in the range of 10 ~ 7 ~ 10 ~ (11), these formulas may be more accurate to determine the equivalence point. At the same time, satisfactory results have also been obtained for mixtures of acids with nearly equal intensities, ie it is also possible to measure two acids with a stability constant of only 0.5 units with an error of less than 1%.
