摘要
来文根据弱酸(碱)平衡体系中质子条件式和弱酸(碱)的分布系数,考虑溶剂水本身质子自递过程产生的影响,导出一个精确计算弱酸(碱)平衡体系pH值的通用公式。应用PAD编程技术,利用计算机对此通用公式进行数值解,可供精确计算各种不同弱酸(碱)平衡体系的pH值。
This paper derives an universal equation for calculating the pH value of a weak acid and weak base equilibrium system. This equation is based on the protou condition equation and distribution coefficient in a weak acid and weak base equi- librium system, with the influence of protonlysis of solvent water under consideration. A numerical solution on the equation is undertaken by using PAD programming technique so as to calculate accurately the pH values of weak acid and weak base equilibrium syctems.
