Current Question (ID: 8523)

Question:

\text{Assertion (A): The aqueous solution of } \text{CH}_3\text{COONa is alkaline in nature.} \text{Reason (R): Sodium acetate undergoes anionic hydrolysis.}

Options:

1. $\text{Both (A) and (R) are true and (R) is the correct explanation of (A).}$
2. $\text{Both (A) and (R) are true but (R) is not the correct explanation of (A).}$
3. $\text{(A) is true but (R) is false.}$
4. $\text{Both (A) and (R) are false.}$

Solution:

\text{Hint: Acetic acid is a weak acid.} \text{Explanation:} \text{The aqueous solution of } \text{CH}_3\text{COONa} \text{ is alkaline in nature. Because } \text{CH}_3\text{COONa} \text{ dissociates and forms } \text{CH}_3\text{COO}^- \text{ and } \text{Na}^+\text{. The anion undergoes anionic hydrolysis by reacting with water. The reaction is as follows:} \text{CH}_3\text{COO}^- + \text{H}_2\text{O} \rightleftharpoons \text{CH}_3\text{COOH} + \text{OH}^- \text{Due to the formation of hydroxide ions, pH increases and the aqueous solution of } \text{CH}_3\text{COONa} \text{ becomes alkaline in nature.} \text{Hence, Assertion is a true statement but Reason is false.}
