Vedclass · Answer

(D) salt that turns blue litmus red in an aqueous solution must be acidic in nature.This occurs when a salt is formed from a strong acid and a weak base.$KCN$ is a salt of a strong base $(KOH)$ and a weak acid $(HCN)$,making it basic.$Na_2CO_3$ is a salt of a strong base $(NaOH)$ and a weak acid $(H_2CO_3)$,making it basic.$NaNO_3$ is a salt of a strong base $(NaOH)$ and a strong acid $(HNO_3)$,making it neutral.$CuCl_2$ is a salt of a weak base $(Cu(OH)_2)$ and a strong acid $(HCl)$.Due to the hydrolysis of $Cu^{2+}$ ions,the solution becomes acidic,turning blue litmus red.

Which among the following salts turns blue litmus red in its aqueous solution?
