Upon hyderolysis of sodium carbonate, the reaction takes place between:

Options

A. sodium ion and water
B. `Na^(+) and OH^(-)`
C. `CO_(3)^(2-)` and water
D. `CO_(3)^(2-) and H^(+)`

Answer

C

Explanation

`Na_(2)CO_(3)+2H_(2)O Leftrightarrow 2NaOH+H_(2)CO_(3)`
`or 2Na+CO_(3)^(2-)+2H_(2)O` `Leftrightarrow 2Na^(+)+2OH^(-)+H_(2)CO_(3)`
`or CO_(3)^(2-)+2H_(2)O Leftrightarrow 2OH^(-)+H_(2)CO_(3)`
It is anionic hydrolysis.
