NEUTRALIZATION

A neutralization reaction is when an acid and a base react to form water and a salt and involves the combination of H+ ions and OH- ions to generate water.

The neutralization of a strong acid and strong base has a pH equal to 7. 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.

Consider the reaction between HCl and NaOH in water:

HCl(aq)acid+NaOH(aq)base⇋NaCl(aq)salt+H2O(l)water

A weak acid, weak base reaction can be shown by the net ionic equation example:

H+(aq)+NH3(aq) ⇋ NH+4(aq)
