Enthalpy of neutralization is defined as the enthalpy change when 1 mole of acid/base is completely neutralized by base/acid in dilute solution. For strong acid and strong base neutralization net chemical change is H_((aq))^(+) + OH_((aq))^(-) rarr H_(2)O_((l)), Delta H_(r )^(0)-= - 55.84 kJ//mol What is Delta H^(0) for complete neutralisation of strong diacidic base A(OH)_(2) " by" HNO_(3)?

Answer»

`-55.84 KJ`
`-111.68kJ`
55.84 kJ/mol
none of these

Solution :For strong base with strong ACID, `-55.84 rarr1` EQ
diacidic `rArr` 2eq `=2 XX (-55.84) = - 111.68kJ`
