They are used to visually signal the acidity or alkalinity of an aqueous (water-based) solution. pH indicators generally change color over a range of two pH units. 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.
