WebAcid-Base Indicators. Certain organic substances change color in dilute solution when the hydronium ion concentration reaches a particular value. For example, phenolphthalein is a colorless substance in any aqueous solution with a hydronium ion concentration greater than $5.0×10^{-9}\;M$(pH < 8.3). WebWhen an acid is able to completely dissociate, it creates more H+ protons than an acid that can only partially dissociate. This means that this acid has a higher CONCENTRATION of H+ molecules. This concentration is written as [H+] and because it is directly related to pH, it can be used to calculate pH, which you will see later.
