Assertion: Heat of neutralization for both HNO 3 and HCl with NaOH is 53.7 kJ / mole. Reason: NaOH is a strong electrolyte/base.

Question

Assertion: Heat of neutralization for both HNO 3 and HCl with NaOH is 53.7 kJ / mole. Reason: NaOH is a strong electrolyte/base. (A) If both Assertion and Reason are true and the Reason is a correct explanation of the Assertion (B) If both Assertion and Reason are true but Reason is not a correct explanation of the Assertion (C) If Assertion is true but the Reason is false (D) If both Assertion and Reason are false

NaOH is a strong electrolyte and decomposes fully in solution into its ions.

N a O H \to N a^{+} + O H^{-}

Due to high availability of

O H^{-}

ions, both strong acids

H N O_{3}

and HCl are neutralised with equal ease. So equal heat of neutralisation for both.

Q. Assertion: Heat of neutralization for both HNO3​ and HCl with NaOH is 53.7kJ/mole. Reason: NaOH is a strong electrolyte/base.

If both Assertion and Reason are true and the Reason is a correct explanation of the Assertion

If both Assertion and Reason are true but Reason is not a correct explanation of the Assertion

If Assertion is true but the Reason is false

If both Assertion and Reason are false

NaOH is a strong electrolyte and decomposes fully in solution into its ions. NaOH→Na++OH− Due to high availability of OH− ions, both strong acids HNO3​ and HCl are neutralised with equal ease. So equal heat of neutralisation for both.

Q. Assertion: Heat of neutralization for both $H N O_{3}$ and $H Cl$ with $N a O H$ is $53.7 k J / m o l e$ .
Reason: $N a O H$ is a strong electrolyte/base.

NaOH is a strong electrolyte and decomposes fully in solution into its ions.

$N a O H \to N a^{+} + O H^{-}$

Due to high availability of $O H^{-}$ ions, both strong acids $H N O_{3}$ and HCl are neutralised with equal ease. So equal heat of neutralisation for both.
