Which of the following salts undergoes anionic hydrolysis ?

Options

A. `CuSO_(4)`
B. `NH_(4)CI`
C. `FeCI_(3)`
D. `Na_(2)CO_(3)`

Answer

D

Explanation

Anionic hydrolysis means anion reacts with water.
`Na_(2)CO_(3) +2H_(2)O hArr 2NaOH H_(2)CO_(3)`
or `2Na^(+) +CO_(3)^(2-) +2H_(2)O hArr 2Na^(+) +2OH^(-) +H_(2)CO_(3)`
or `CO_(3)^(2-) +2H_(2)O hArr 2OH^(-) +H_(2)CO_(3)`
