The same principle applies to the acidity of organic molecules. We can also say, the stronger the tendency of a compound to donate a proton, the stronger acid it is. The more the acid dissociates into a proton, the stronger it is. So, one measure of acid strength is the extent of its dissociation which indicates the amount of protons or hydronium ions that it produces in the solution. Hydrochloric acid is a strong acid because it completely ionizes in aqueous solutions. In this case, the conjugate base of the acid is the chloride ion. The general equation for acid dissociation can be shown as:įor a specific example, we can look at the dissociation of hydrochloric acid: According to the Arrhenius theory, acids dissociate in water to form protons (H +). Let’s first define the meaning of a strong acid.
