Neutralisation

The reaction between an acid and a base is known as a neutralisation reaction. The acid and the base neutralise each other and water is produced.

The pH of an acid that has been completely neutralised will be seven.

NOTE:

The H⁺ ions (hydrogen) in the acid react with the OH^- (hydroxide) ions in the base to produce water.

H⁺ (aq) + OH^- → H₂O

When H⁺ ions collide with OH^- ions, water is produced.
