Statement-I : The enthalpy of neutralization of the reaction between HCl and NaOH is -13.7 kCal/mol. If the enthalpy of neutralization of oxalic acid (H_(2)C_(2)O_(4)) by a strong base is -25.4 kCal/mol, then the enthalpy change (|Delta_(r)H|) of the process H_(2)C_(2)O_(4) rarr 2H^(+)+C_(2)O_(4)^(2-) is 11.7 kCal/mol. Statement-II : H_(2)C_(2)O_(4) is a weak acid.

The enthalpy of neutralization of oxitic acid by strong acid is 25.4 kcal mol^(-1) . The enthalpy of neutralization of strong acid and strong base is -13.7 kcal equil^(-1) . The enthalpy of dissociation of H_(2)C_(2)O_(4)hArr2H^(+)+C_(@)O_(4)^(2-) is

H_(2)Cr_(2)O_(7) on heating with aqueous NaOH gives

The heat of neutralisation of oxalic acid is -25.4 kcal mol^(-1) using strong base, NaOH . Hence, the enthalpy change of the process is H_(2)C_(2)O_(4) hArr 2H^(o+) +C_(2)O_(4)^(2-) is

The heat of neutralisation of oxalic acid is -25.4 kcal mol^(-1) using strong base, NaOH . Hence, the enthaly change of the process is H_(2)C_(2)O_(4) hArr 2H^(o+) +C_(2)O_(4)^(2-) is
