Question

Assertion :Ammonium chloride is acidic in liquid ammonia solvent. Reason: $N{H}_{4}Cl\rightleftharpoons N{H}_4^{+}+C{l}^{-}$
$2N{H}_3⟶N{H}_2^{-}+N{H}_4^{+}$
In $N{H}_3,N{H}_4^{+}$ is formed which is one of the ion of $N{H}_{4}Cl.N{H}_4^{+}$ is an acid

Read the above assertion and reason and choose the correct option regarding it.

• A. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
• B. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
• C. Assertion is correct but Reason is incorrect
• D. Both Assertion and Reason are incorrect

Answer 1

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion

The equilibrium expression for the dissociation of ammonium chloride is $N{H}_{4}Cl\rightleftharpoons N{H}_4^{+}+C{l}^{-}$
The expression for the dissociation of ammonia solvent is $2N{H}_3⟶N{H}_2^{-}+N{H}_4^{+}$
In $N{H}_3,N{H}_4^{+}$ is formed which is one of the ion of $N{H}_{4}Cl.N{H}_4^{+}$ is an acid
Hence, ammonium chloride is acidic in liquid ammonia solvent.
