Question

A solution of $FeC{l}_3$ in water acts as acidic due to______

• A. hydrolysis of $F{e}^{3+}$
• B. acidic impurities
• C. dissociation
• D. ionisation

Answer 1

The correct option is A hydrolysis of $F{e}^{3+}$

$FeC{l}_3+3H_{2}O\rightleftarrows Fe(OH{)}_3+3HCl$.

Strong acid and weak base.
As $HCl$ formed which is strong acid,so the solution becomes acidic,due to hydrolysis.
