neutralize an Acid or Base a source of hydroxide ions (OH —) or. hydrogen ions (H +) are required respectively. An acid must be neutralized with a base, which by definition is characterized by an excess of OH — ions. Likewise, a base must be neutralized with an acid, which by definition is characterized by an excess of H + ions. OH — + H + = H. 2. O (pH 7)
