$7.25. 10. 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. A common use is for measuring the presence of carbonic acid in a liquid (1). Thymol blue: 8.0-9.6: 1-5 drops 0.1% aq.
