Question

$ NH_4Cl $ is acidic due to

• A. cationic hydrolysis
• B. anionic hydrolysis
• C. its ionic nature
• D. $ pH > 7 $

Answer 1

Answer: (A)

$NH _{4} Cl + H _{2} O \to NH _{4} OH + HCl$

or $NH _{4}^{+}+ Cl ^{-}+ H _{2} O\to NH _{4} OH + H ^{+}+ Cl ^{-}$

or $\underset{\text{cation}}{NH^{+}_{4}}+H_{2}O \to NH_{4}OH +H^{+}$

Due to the presence of $H ^{+}$, after cationic hydrolysis, in the solution, the solution of $NH _{4} Cl$ is acidic.
