Question

Theories of indicators and selection of indicator for acid base titration

Answer 1

Theory of Indicators/choice of indicator/acid base indicator. ... An indicator is a substance which is used to determine the end point in a titration. In acid-base titrations , organic substances (weak acids or weak bases) are generally used as indicators . They change their colour within a certain pH range?
