Question

When `BaCl_(2)` is added to an aqueous salt solution, a while precipitate is obtained. The anion among `CO_(3)^(2-), SO_(3)^(2-)` and `SO_(4)^(2-)` that was present in the solubtion can be :
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 these

Answer 1

Correct Answer - D
None of these anions can be present in solution since `BaCO_(3), BaSO_(4)` and `BaSO_(3)` are all precipitated and are insoluble in water.
