A) \[C{{H}_{3}}COONa\]
B) \[NaCl\]
C) \[N{{H}_{4}}OOCC{{H}_{3}}\]
D) \[N{{H}_{4}}Cl\]
Correct Answer: D
Solution :
\[N{{H}_{4}}Cl\]is a salt of weak base\[(N{{H}_{4}}OH)\]and strong acid\[(HCl),\]thus undergoes cationic hydrolysis and provides H+ ions that make the solution acidic ie, pH is very less or less than 7. \[N{{H}_{4}}Cl+{{H}_{2}}O\xrightarrow{{}}N{{H}_{4}}OH+HCl\]or \[NH_{4}^{+}+{{H}_{2}}O\xrightarrow{{}}N{{H}_{4}}OH+{{H}^{+}}\]
