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

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 mol of `H^(+)` ions and 1 mol `OH^(-)` ions to form water.

`H_2O `

` NaOH`

`CS_2`

`HCl`
