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

Options

A. neutralisation leads to the formation of a salt and water
B. strong acids and bases are ionic substances
C. acids always give rise to `H^(+)` ions and bases always furnish `OH^(-)` ions
D. the net chemical change involve the combination of `1` mol of `H^(+)` ions and ions `OH^(-)` ions to form water.

Answer

D

Explanation

The enthalpy of neutralisation of all strong acids and strong base has the same value because the net chemical change involved is the combination of `1 mol` of `H^(+)` and `1 mol` of `OH^(-)` ions to form water
