Question

When BaCl2 is added to an aqueous salt solution, a white precipitate is obtained. The anion among CO3 2-, SO3 2- and SO4 2- that was present in the solution can be : (A) CO3 2- but not any of the other two (B) SO3 2- but not any of the other two (C) SO4 2- but not any of the other two (D) Any of them

∵ If CO 32-, SO 32- and SO 42- are present alongwith BaCl 2, these can also show white precipitate (as precipitate of all these are also white).

Q. When $B a C l_{2}$ is added to an aqueous salt solution, a white precipitate is obtained. The anion among $C O_{3}^{2 -}, S O_{3}^{2 -}$ and $S O_{4}^{2 -}$ that was present in the solution can be :

$C O_{3}^{2 -}$ but not any of the other two

$S O_{3}^{2 -}$ but not any of the other two

$S O_{4}^{2 -}$ but not any of the other two

Any of them

$∵$ If $C O_{3}^{2 -}, S O_{3}^{2 -}$ and $S O_{4}^{2 -}$ are present alongwith $B a C l_{2}$ , these can also show white precipitate (as precipitate of all these are also white).
