Heat of neuralisation is amount of heat evolved or absorbed when `1g-` equivalent of an acid reacts with `1g-` equivalent of a base in dilute solution . If weak acid or weak bae are neutralised, the heat released during neutralisation is somewhat lesser than `-13.7kcal` or `-57.27 kJ` . Het of neutralisation is also referred as heat of formation of water from `H^(+)` and `OH^(-)` ions `i.e., H^(+)+OH^(-) rarr H_(2)O, DeltaH=-13.7kcal. `  Heat of neutralisatio of `HF` and acetic acid respectively are `(` in `kcal):`
