几种酸碱溶液体系PH值的计算

采用解析法，先分别用基本公式算出酸组份的［Ｈ＋］ａ及碱组份的［ＯＨ－］ｂ，然后根据溶液的组成不同，采用不同的加合式，以算出整个溶液的酸（碱）度。进行计算时，不论什么样的体系，均按一定顺序进行，严格按误差要求取舍数据，该法有理论依据，计算结果符合误差要求，方法适用性广，有一定系统性，不解高次方程。

CALCULATING THE PH VALUE OF SEVERAL ACID-BASE SOLUTION SYSTEMS

To calculate the pH values of acid-base solutions,the author deduced a new system. First, the hydrogen ion concentration of acid and the hydroxide ion concentration of base in the solution were independently calculated, then they were put together for the calculation of pH value of the add-merge formulas. This method is simple and universally applicable, and doesn't need to solve equations of higher degree.
