Question

Assertion (A): The aqueous solution of $C{H}_{3}COONa$ is alkaline in nature.
Reason (R): Acetate ion undergoes anionic hydrolysis
The correct answer is

• A. both (A) and (R) are true and (R) is the correct explanation of (A).
• B. both (A) and (R) are true but (R) is not the correct explanation of (A).
• C. (A) is true but (R) is not true.
• D. (A) is not true but (R) is true.

Answer 1

Answer: (A)

$C{H}_{3}COONa+H_{2}O\to C{H}_{3}COOH+NaOH$
The above process takes place in following steps
$C{H}_{3}COONa$ lonisation $C{H}_{3}CO{O}^{-}+N{a}^{+}$in aqueous solution strong base
$C{H}_{3}CO{O}^{-}+H_{2}O\to C{H}_{3}COOH+O{H}^{-}$
Acetate ion undergoes hydrolysis and the resulting solution is slightly basic due to excess of $O{H}^{-}$ions.
