What do we mean by neutralisation?

Neutralization is a chemical reaction (also called a water forming reaction since a water molecule is formed during the process) in which an acid and a base or alkali (soluble base) react to produce salt and water (H2O). During the process, hydrogen ions H+ (a bare proton) from the acid (proton donor) or a hydronium ion H3O+ and hydroxide ions OH− or oxide ions O2− from the base (proton acceptor) react together to form a water molecule H2O. In the process, a salt is also formed when the anion from acid and the cation from base react together.
