$CH_3COONa$

Vedclass · Answer

(B) $NH_4Cl$ is a salt of a strong acid $(HCl)$ and a weak base $(NH_4OH)$,so it is acidic.$CH_3COONa$ is a salt of a weak acid $(CH_3COOH)$ and a strong base $(NaOH)$,so it is basic.$Na_2SO_4$ is a salt of a strong acid $(H_2SO_4)$ and a strong base $(NaOH)$,so it is neutral.$CH_3COONH_4$ is a salt of a weak acid $(CH_3COOH)$ and a weak base $(NH_4OH)$,so its nature depends on the relative values of $K_a$ and $K_b$.In $CH_3COONa$,the $CH_3COO^{-}$ ion undergoes hydrolysis: $CH_3COO^{-} + H_2O \rightleftharpoons CH_3COOH + OH^{-}$.Since $OH^{-}$ ions are produced,the solution is basic.

Which of the following $0.1 \ M$ solutions of compounds will be basic in nature?
