$CuCl_2$

Vedclass · Answer

(A) $1$. $CuCl_2$: Salt of a strong acid $(HCl)$ and a weak base $(Cu(OH)_2)$. The hydrolysis of $Cu^{2+}$ ions produces $H^+$ ions,making the solution acidic.$2$. $NH_4CN$: Salt of a weak acid $(HCN)$ and a weak base $(NH_4OH)$. Since $K_a (HCN) $3$. $KCN$: Salt of a weak acid $(HCN)$ and a strong base $(KOH)$. The solution is basic due to the hydrolysis of $CN^-$ ions.$4$. $CH_3COONa$: Salt of a weak acid $(CH_3COOH)$ and a strong base $(NaOH)$. The solution is basic due to the hydrolysis of $CH_3COO^-$ ions.

Which among the following salt solutions in water is acidic in nature?
