Aqueous solution of `FeCl_(3)` is acidic because of

Options

A. Hydrolysis
B. Anionic hydrolysis
C. Cationic hydrolysis
D. Dissociation

Answer

C

Explanation

Aqueous solution of `FeCl_(3)` dissociates as follows,
`FeCl_(3) hArr Fe^(3+) + 3CI^(-)`
`Fe^(3+) + 3H_(2)O hArr Fe(OH)_(3) + 3H^(+)`
There is excess of `H^(+)` ions formed due to cationic hydrolysis which makes the solution acidic.
