Vedclass · Answer

(D) $1$. $KNO_3$ is a salt of a strong acid $(HNO_3)$ and a strong base $(KOH)$, so its aqueous solution is neutral $(pH = 7)$.$2$. $Na_2CO_3$ is a salt of a weak acid $(H_2CO_3)$ and a strong base $(NaOH)$, so its aqueous solution is basic $(pH > 7)$.$3$. $CH_3COONa$ is a salt of a weak acid $(CH_3COOH)$ and a strong base $(NaOH)$, so its aqueous solution is basic $(pH > 7)$.$4$. $CuCl_2$ is a salt of a strong acid $(HCl)$ and a weak base $(Cu(OH)_2)$. Due to the hydrolysis of the $Cu^{2+}$ ion, the solution becomes acidic $(pH < 7)$.

Which of the following aqueous solutions of salts has $pH < 7$ at $298 \text{ K}$?
