The heat of neturalisation between weak ...

The heat of neturalisation between weak acid (HNC) and strong base (NaOH) is `(-56.1)` kJ/mole. The neutralisation between strong acid (HCI)and strong base (NaOH) is `(-57.3)` kJ/mol. If the weak acid (HNC) is `80%` ionised in the above solution then calculate the heat of ionisation (in J/mol) for `100%` ionisation of HCN in the above solution.

Explain why heat of neutralisation of strong acid and weak base is less than 57.1 kJ .

Heat of neutralisation of a strong dibasic acid in dilute solution by NaOH is nearly :

The heat of neutralization of any strong acid and strong base is always constant and DeltaH=-57.3kJ . This because.

The enthalpy of formation of H_(2)O(l) is -280.70 kJ/mol and enthalpy of neutralisation of a strong acid and strong base is -56.70 kJ/mol. What is the enthalpy of formation of OH^(-) ions?
