弱酸(碱)溶液[H^+]([OH^-])近似计算条件

The Condition for the Approximate Calculation of the Solution[H^+]([OH^-])of weak Acid(Base)

本文以相对误差概念,对弱酸(碱)溶液[H^+]([OH^+])计算时。忽略水电离H^+及采用最简公式进行近似计算的条件进行了讨论。

In this article we deal with the condition of doing the approximate calculation by means of the most simple formula,according to the concept of relative error,when calculating weak acid (base)solution [H^+]([OH^-])and disregarding the ionization[H^+]of water.
