A solution of in water acts acidic. This is primarily due to the: — Ionic Equilibrium Chemistry Question

💡 Solution & Explanation

$FeCl_3$ is a salt of a weak base ($Fe(OH)_3$) and a strong acid (HCl). The weak base cation, $Fe^{3+}$, undergoes cationic hydrolysis ($Fe^{3+} + 3H_2O \rightleftharpoons Fe(OH)_3 + 3H^+$), generating $H^+$ and making the solution acidic.
