Neutralisation

Neutralisation is the reaction between an acid and a base to form a salt and water

Hydrogen ions (H+) react with a base to form a salt and neutral water. The ionic equation for neutralisation is

H+(aq) + OH-(aq) → H2O(l)

A salt is a compound formed when the H+ ions in an acid are replaced by metal ions or ammonium ions.
