Hydrochloric Acid and Sodium Hydroxide Neutralization

HCl + NaOH → NaCl + H₂O

Tổng quan

The quintessential strong acid-strong base neutralization reaction producing sodium chloride and water. The net ionic equation is simply H⁺ + OH⁻ → H₂O. The enthalpy of neutralization for any strong acid-strong base pair is approximately -57.1 kJ/mol because the reaction is fundamentally the same.
