Vedclass · Answer

(A) Aluminum chloride $(AlCl_3)$ is a salt of a strong acid $(HCl)$ and a weak base $(Al(OH)_3)$.In an aqueous solution,the $Al^{3+}$ ion undergoes hydrolysis as follows:$Al^{3+}(aq) + 3H_2O(l) \rightleftharpoons Al(OH)_3(s) + 3H^+(aq)$.Since $H^+$ ions are produced in the solution,the aqueous solution of $AlCl_3$ becomes acidic.This process is known as cation hydrolysis.

An aqueous solution of aluminum chloride is acidic due to $........$.
