A solution of

\mathrm{FeC}{\mathrm{l}_3}

in water acts as acidic due to:

View answer and explanation

Correct option: C

Hydrolysis of

\mathrm{F}{\mathrm{e}^{3 + }}

Option C (Hydrolysis of

\mathrm{F}{\mathrm{e}^{3 + }}

) is correct because the ferric ion undergoes hydrolysis, releasing

{\mathrm{H}^ + }

ions and making the solution acidic.
