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.
