$NH_4F$

Vedclass · Answer

(B) An acidic solution turns blue litmus paper red. * $NH_4F$ is a salt of a weak acid $HF$ $(K_a = 7.2 	imes 10^{-4})$ and a weak base $NH_4OH$ $(K_b = 1.8 	imes 10^{-5})$. Since $K_a > K_b$,the aqueous solution of $NH_4F$ is acidic in nature. * $NH_4CN$ is a salt of a weak acid $(HCN)$ and a weak base $(NH_4OH)$,where $K_b > K_a$,making it basic. * $CH_3COONa$ is a salt of a weak acid $(CH_3COOH)$ and a strong base $(NaOH)$,making it basic. * $CH_3COONH_4$ is a salt of a weak acid $(CH_3COOH)$ and a weak base $(NH_4OH)$ with $K_a \approx K_b$,making it neutral.
