WebThis equation can be rearranged as follows. This shows how pKa and pH are equal when exactly half of the acid has dissociated ( [A - ]/ [AH] = 1). If the pH changes by 1 near the pKa value, the dissociation status of the acid changes by an extremely large amount. In the case of acetic acid, for example, if the solution's pH changes near 4.8, it ...
