Vedclass · Answer

(D) $Al_2(SO_4)_3$ is a salt of a strong acid $(H_2SO_4)$ and a weak base $(Al(OH)_3)$.When dissolved in water,it undergoes hydrolysis.The $Al^{3+}$ ion reacts with water to form $Al(OH)_3$ and $H^+$ ions.$Al^{3+} + 3H_2O \rightleftharpoons Al(OH)_3 + 3H^+$.Due to the presence of excess $H^+$ ions,the resulting aqueous solution is acidic in nature.
