A pH indicator is a halochromic chemical compound added in small amounts to a solution so the pH (acidity or basicity) of the solution can be determined visually.Hence a pH indicator is a chemical detector for hydronium ions (H 3 O ) or hydrogen ions (H ) in the Arrhenius model.Normally the indicator causes the color of the solution to change depending on the pH.
