Enthalpy of neutralisation of all strong acids and strong bases has the same value because

Answer»

Neutralisation LEADS to the formation of a salt and water
Strong acid and bases are ionic substances
Acids always FURNISH `H^(+)` ions and bases always furnish `OH^(-)` ions
The net chemical change involves the combination of 1 mole of `H^(+)` ions and 1 mol `OH^(-)` ions to form water.

Solution :NEUTRALIZATION of strong acid and strong base is NOTHING but REACTION between `H^(+) and OH^(-)` so the heat of neutralization value remains constant
