Sodium Hydroxide and Hydrochloric Acid Neutralization

NaOH + HCl → NaCl + H2O

개요

Sodium hydroxide reacts with hydrochloric acid to produce sodium chloride and water. This is the archetypal neutralization reaction, producing exactly neutral pH 7 solution because both the acid and base are strong. The heat of neutralization is approximately -57.1 kJ/mol for any strong acid-strong base pair.
