The reaction of an aqueous hydrochloric acid solution with an aqueous sodium hydroxide solution is represented by the neutralization chemical equation:

HCl (aq) + NaOH (aq) - -> NaCl (aq) + H2O (l) + Energy

Explanation:

This is called a neutralization reaction, which is a reaction in which an acid and a base react to form water and a salt. This reaction involves the combination of H + ions and OH - ions to generate water. pH equal to 7 is a neutralization of a strong acid and strong base. The neutralization of a strong acid and weak base will have a pH of less than 7, and conversely, the resulting pH when a strong base neutralizes a weak acid will be greater than 7.

When a solution is neutralized, it means that salts are formed from equal weights of acid and base. The amount of acid needed is the amount that would give one mole of protons (H+) and the amount of base needed is the amount that would give one mole of (OH-).
