摘    要:以物料平衡电荷平衡和化学平衡为基础,通过严格的数学推导提出一种新的滴定分析理论-相对滴定法,它是以相同滴定状态下被测物质的量与滴定剂体积之间的线性关系为基础,通过仪器分析方法进行定量计算。该法在滴定过程中的任一状态都成立,不需确定等当点,从根本上消除和终点误差,不仅适用于滴定突跃很体系,还适用于滴定反应未知的滴定过程。

关 键 词:相对滴定法  一元弱酸  电位滴定法  滴定分析法

Abstract:elative titration method is a new analytical theory based on strict mathematical treatments to the equations of mass balance, charge balance and chemical equilibrium. The relative titration method can be applied not only to the systems which have small equivalent point breaks but also the systems in which the chemical reactions are not ascertained during the titration. In this article, the factors which affect the precision and sensitivity of the relative titration and the principle of selecting optimum experiment conditions are determined by theoretical analysis of errors in the system of monoprotic weak acid titrated by strong base. The theoretical conclusions are compatible with the experimental results in the titration of H3BO3 by NaOH.
Keywords:elative titration  potentiometric titration  monoprotic weak acid
