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.


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.
