Assertion (A): The aqueous solution of `CH_(3)COONa` is alkaline in nature.
Reason (R): Acetate ion undergoes anionic hydrolysis.
The correct answer is

Options

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 the true but (R) is not true
D. (A) is not true but (R) is true

Answer

A

Explanation

The reaction of `CH_(3)COONa` with water is as follows,
`CH_(3)COONa + H_(2)O hArr CH_(3)COOH + NaOHunderset("strong base")`
The ionisation of `CH_(3)COONa` is given by,
`CH_(3)COONa hArr CH_(3)COO^(-) + Na^(+)`
`CH_(3)COO^(-) + H_(2)O rarr CH_(3)COOH + OH^(-)`
The aqueous solution of `CH_(3)COONa` is alkaline in nature because the acetate ion undergoes anionic hydrolysis to form sodium hydroxide.
