What is a neutralisation reaction? Give two examples.

Explanation

A reaction in which an acid and base react with each other to give a salt and water is termed as neutralization reaction. In this reaction, energy is evolved in the form of heat. For example:
`{:(NAOH,+,HCl,to,NaCl,+,H_(2)O),(("base"),,("Acid"),,("Salt"),,("Water")):}`
(ii) During indigestion (caused due to the production of excess of hydrochloric acid in the stomach), we administer an antacid (generally milk of magnesia,`Mg(OH)_(2)`, which is basic in nature). The antacid neutralizes the excess of acids and thus gives relief from indigestion.
`Mg (OH)_(2)+2HCl to MgCl_(2)+2H_(2)O`
