A neutralisation reaction occurs when an acid and a base react to form water and a salt, often accompanied by the release of heat. This is a chemical change because new substances are formed, and it is typically considered irreversible under standard conditions.

Neutralisation reaction
Neutralisation reaction is a chemical and irreversible change that occurs when an acid reacts with a base to form a salt and water.
Explanation
When an acid and a base react, they neutralize each other's properties. The H+ ions from the acid combine with the OH- ions from the base to form water, while the remaining ions combine to form a salt. This reaction is irreversible because the reactants are completely consumed to form new products, and it is not easily reversed.
Chemical change
Neutralisation reaction is a chemical change because new substances with different properties are formed. Acids and bases have distinct chemical properties, and when they react, the resulting salt and water have different properties from the original reactants.
Irreversible change
Neutralisation reaction is irreversible because once the reactants have combined to form the products, it is difficult to separate them back into the original substances. The reaction proceeds in one direction only, and it is not easily reversed.
In conclusion, neutralisation reaction is a chemical and irreversible change that occurs when an acid and a base react to form a salt and water. This reaction is not easily reversible, as the new substances formed have different properties from the original reactants.
