A) Ammonium chloride
B) Ammonium acetate
C) Ammonium sulphate
D) Sodium acetate
Correct Answer: D
Solution :
Sodium acetate is a salt of strong base \[(NaOH)\] and weak acid \[(C{{H}_{3}}COOH).\] In aqueous solution it gets hydrolysed as \[C{{H}_{3}}COONa+{{H}_{2}}O\xrightarrow{{}}C{{H}_{3}}COOH+NaOH\]or \[C{{H}_{3}}CO{{O}^{-}}+N{{a}^{+}}+{{H}_{2}}O\xrightarrow{{}}C{{H}_{3}}COOH\] \[+\,N{{a}^{+}}+O{{H}^{-}}\] or\[C{{H}_{3}}CO{{O}^{-}}+{{H}_{2}}O\xrightarrow{{}}C{{H}_{3}}COOH+O{{H}^{-}}\] Because of the excess of\[[O{{H}^{-}}]\]in aqueous solution, its solution is basic in nature. Aqueous solution of salt of strong acid and weak base is acidic and that of strong acid and strong base is neutral.You need to login to perform this action.
