$FeCl_3$

Vedclass · Answer

(C) The acidity of a salt solution depends on the extent of hydrolysis,which is determined by the charge density of the cation. $Fe^{3+}$ and $Al^{3+}$ are highly acidic due to high charge density. However,$FeCl_3$ undergoes hydrolysis to form $Fe(OH)_3$ and $HCl$. Comparing the acidity,$FeCl_3$ is generally considered more acidic than $AlCl_3$ because $Fe^{3+}$ has a higher charge-to-size ratio and forms a more acidic solution upon hydrolysis in aqueous media. Therefore,the correct answer is $C$.
