Titration Errors

Abstract

There are two types of titration errors, systematic and random errors. Systematic errors can be easily estimated with the help of pH-logci diagrams. The diagrams are especially helpful for choosing the best color indicators. The diagrams are also useful to find, in the case of alternative titrations, the one with the smallest random error (see Sect. 5.7). The following estimation of systematic titration errors is confined to cases where the autoprotolysis of water can be ignored, because a comprehensive and detailed treatment including the autoprotolysis would be completely beyond the scope of this book, and also only of importance in rather exotic cases of very dilute solutions.
