Does liquid base react with liquid acid? Why? Why?Liquid bases will react with liquid acid. This was because the liquid base usually contained a hydrogen ion (H), and the liquid acid usually contained a hydrogen ion (H). When the two met, the hydrogen ion and the hydrogen ion would combine to form water (H O). At the same time, the positive and negative ions in the liquid acid and the liquid base would combine to form a salt. This reaction process was called the acid base neutralizing reaction. For example, the reaction between sulfuric acid (HQ) and soda ash (NaOx) would produce NaCl2 and water, and the reaction equation was HQ + NaOx → NaCl2 + H2O.
