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. Natural pH indicator foods change colors as the pH of the solution changes. From purple to blue, green, even yellow!
