Assertion (A): The heat of neutralisation of perchloric acid, HCIO_(4) , with NaOH is same as that of HCI with NaOH . Reason (R ) : Both HCI and HCIO_(4) are strong acids.

Statement-1: Heat of neutralisation of H_(3)PO_(4) with NaOH is more than that of HCl with NaOH. Statement-2: H_(3)PO_(4) is a triprotic acid and hence release more heat on complete neutralization, while HCl is a monoprotic acid.

Assertion : Heat of neutralisation of HNO_(3) and NaOH is same as that of HCl and KOH. Reason : Both HNO_(3) and HCl are storng acids and NaOH and KOH are strong bases.

Assertion(A) : Heat of neutralisation of HCl and NaOH is same as that of H_(2)SO_(4) with NaOH . Reason(R ) : HCl , H_(2)SO_(4) and NaOH are all strong electrolytes.

Statement-1: Heat of neutralization of HCl by NaOH is more than that by NH_(4)OH Statement-2: NaOH is stronger base than NH_(4)OH

Assertion : Heat of neutralization for both H_(2)SO_(4) and HCl with NaOH is 53.7 kJ mol^(−1) . Reason : Both HCl and H_(2)SO_(4) are strong acids.

Assertion : Heat of neutralisation of nitric acid with NaOH is same to that of HCl and NaOH. Reason : In both cases strong acid and strong bases are neutralised. H^(+)+OH^(-)rarrH_(2)O .
