摘要:

用二元弱酸滴定的林邦滴定曲线方程推导第一和第二滴定突跃绝对值,用第一和第二滴定突跃绝对值推导二元弱酸第一和第二级解离的H+准确滴定的条件,并将其应用于多元弱酸的准确滴定。

关键词: 多元弱酸滴定, 滴定突跃绝对值, 滴定曲线方程

Abstract:

Using the Ringbom equation for titration of dibasic acids, the first and second titration jumps were derived. As followed, the accurate conditions for sequential titration of dibasic weak acids were derived with the first and second titration jumps. And the deduction is also applied to titration of polyprotic acids.

Key words: Polyprotic acid titration, Titration jump, Titration curve equation
