一元或多元弱酸(碱)溶液体系存在主要由离解平衡决定的缓冲性质,而对不同pH值下缓冲容量的了解,将有助于我们对各种一元或多元弱酸(碱)缓冲性质的更好掌握,从而将对溶液平衡的深入研究,实验及教学产生实际意义。赵藻藩等基于Hesse的工作,推出了以酸碱组分的分布系数所表示的单个多元弱酸体系的缓冲容量公式。本文进一步推导并建立了由若
One or more weak acid (base) solution systems exist mainly in the buffer properties that are determined by the dissociation equilibrium, and knowledge of the buffer capacity at different pH values will help us to better the buffering properties of various mono- or polybasic weak acids (bases) Mastery, which will have practical significance for the in-depth study of solution balance, experiment and teaching. Based on the work of Hesse, Zhao Zhaofan et al. Introduced a buffer capacity formula for a single multivariate weak acid system represented by the distribution coefficient of acid-base components. This article further derives and establishes by
