一元强碱滴定一元弱酸溶液的林邦滴定曲线方程及其应用

The Ringbom Equation for Titration of Monoprotic Acids and Its Application

以林邦副反应思想为基础,用质子条件式PBE、物料平衡式MBE、滴定分数和条件稳定常数等知识推导出一元强碱滴定一元弱酸溶液的林邦滴定曲线方程,并用滴定曲线方程讨论了滴定开始至化学计量点时任意一点p H的计算。

The Ringbom equation for titration of monoprotic acids was derived based on proton condition equa- tion, mass balance equation, titrated fraction as well as the conditional stability constant. The developed Ringbom equation was applied to calculation of pH at any titrated fraction before reaching the stoichiometry point.
