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 (H3O+) or hydrogen ions (H+) in the Arrhenius model. Normally, the indicator causes the color of the solution to change depending on the pH. Indicators can also show change in other physical properties; for example, olfactory indicators show change in their odor. The pH value of a neutral solution is 7.0.
A compound is the combination of elements resulting in a chemical reaction/change. Some compounds are ionic which measn they are formed by combining ions. All ionic compounds include salt and hydroxides. An ionic compound is neutral. The formula for ammonium phosphate is (NH4)3PO4 NaI and Na3PO4.
