When BaCl_2 is added to an aqueous salt 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

Correct answer: (D) Any of them. ∵ If CO_3^2-, SO_3^2- and SO_4^2- are present alongwith BaCl_2 , these can also show white precipitate (as precipitate of all these are also white ).

Q17 / 155 · WBJEE 2017 · Chemistry

When $\mathrm{BaCl}_{2}$ is added to an aqueous salt solution, a white precipitate is obtained. The anion among $\mathrm{CO}_{3}^{2-}, \mathrm{SO}_{3}^{2-}$ and $\mathrm{SO}_{4}^{2-}$ that was present in the solution can be

A
$\mathrm{CO}_{3}^{2-}$ but not any of the other two
B
$S O_{3}^{2-}$ but not any of the other two
C
$\mathrm{SO}_{4}^{2-}$ but not any of the other two
Correct answer
D
Any of them

Solution

$\because$ If $\mathrm{CO}_{3}^{2-}, \mathrm{SO}_{3}^{2-}$ and $\mathrm{SO}_{4}^{2-}$ are present alongwith $\mathrm{BaCl}_{2}$, these can also show white precipitate (as precipitate of all these are also white ).

Hence, the correct answer is option: 'D'.

When $\mathrm{BaCl}_{2}$ is added to an aqueous salt solution, a white precipitate is obtained. The anion among $\mathrm{CO}_{3}^{2-}, \mathrm{SO}_{3}^{2-}$ and $\mathrm{SO}_{4}^{2-}$ that was present in the solution can be
