Some chemical compounds, when dissolved in water, dissociate to yield hydrogen ions (H+, e.g., protons) and are called acids. Other compounds called bases yield hydroxide ions (OH−), when dissolved in water. The relative strength of an acid or base is related to the degree of dissociation that the compound undergoes. A strong acid is one that dissociates completely to yield a relatively large number of hydrogen ions, whereas the strong base is a compound that yields a relatively large number of hydroxide ions.
