Statement `:` Heat of neutralisation can be given as `:`
`H^(+)+OH^(-) rarr H_(2)O, DeltaH=-13.6 kcal.`
Explanation `:` Heat of neutralisation can be alternatively defined as heat of formation of water.

Heat of neutralisation of H_2SO_4 with NaOH is - x KJ. Then the heat of ionisation of water is

H_(2)O(g) rarr H_(2)O(l), DeltaH =- 40.7 kJ DeltaH is the heat of……………….of water.

H_(2)O(g) rarr H_(2)O(l), DeltaH =- 40.7 kJ DeltaH is the heat of……………….of water.

Delta_(f)H(H_(2)O) =- 68 kcal mol^(-1) and DeltaH of neutralisation is -13.7 kcal mol^(-1) , then the heat of formation of overset(Theta)OH is

Delta_(f)H(H_(2)O) =- 68 kcal mol^(-1) and DeltaH of neutralisation is -13.7 kcal mol^(-1) , then the heat of formation of overset(Theta)OH is

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):

If Weak acid or weak base are neutralised ,the heat relealised , the heat released during neutralisatiojn is somewhat lesser than -13.7 kcal or -57.27Kj .Heat of neutralistion is also referred to as heat of formation of water from H^(+) and OH^(-) ionsi.e ., H^(+)OH^(-)to H_(2)O, Deltah=-13.7kcal Magnitude of heat of neutralistion of Hi and acetic acid respectively are (in kcal ) buy strong base are:

H_(2)O(l) rarr H_(2)O(s), DeltaH =- 6.01 kJ DeltaH is the heat of ……………….of water.

H_(2)O(l) rarr H_(2)O(s), DeltaH =- 6.01 kJ DeltaH is the heat of ……………….of water.
