Indicators: Definition, Characteristics and Uses! Definition: Certain dyes which can determine the hydrogen ions in a solution are said to be Indicators. Characteristics: 1. The dyes are weak acids (or, less commonly, weak bases). 2. They have the property of dissociating in solution to yield ions of different colours from the un-dissociated molecules. 3. The pH at which dissociation will [...]
