在现行的高等院校分析化学教材中,通常只讨论酸碱滴定误差,对其它滴定类型的滴定误差很少涉及。就对酸,碱滴定误差的讨论来说,有的就具体实例而论,未推出计算滴定误差的公式,有的虽推出计算公式,但不够一般化。有些专著,虽对滴定误差的讨论比较全面,详细,但较烦琐,不够简明。本文根据所测变量在等当点附近对称变化的特点,导出了计算酸、碱(一元)、络合、沉淀(1:1型)滴定体系滴定误差的一般通用公式。
In the current textbooks of analytical chemistry of colleges and universities, usually only the acid-base titration error is discussed, and the titration errors of other titration types are seldom involved. For the discussion of acid and base titration errors, some have not put forward the formula for calculating titration error in terms of specific examples. Although some formulas are introduced, they are not general enough. Some monographs, although the discussion of titration error is more comprehensive and detailed, is more cumbersome and less concise. Based on the characteristics that the measured variables change symmetrically around the equivalence point, the general formula for calculating the titration error of titration system of acid, alkali (mono), complexation and sedimentation (1: 1 type) is deduced.
