When `BaCl_2` is added to an aqueous solution, a white precipitate is obtained. The anion among `CO_3^(2-)`, SO_3^(2-)` and `SO_4^(2-)` that was present in the solution can be -

Options

A. `CO_3^(2-)` but not any of the other two
B. `SO_3^(2-)` but not any of the other two
C. `SO_4^(2-)` but not any of the other two
D. none of them

Answer

D

Explanation

`BaSO_3, BaCO_3 and BaSO_4` are insoluble in water, thus they are precipitated out in aqueous solution.
