A 2 lit solution contains 0.04 mol of each of `[CO(NH_(3))_(5)SO_(4)]Br` and `[CO(NH_(3))_(5)Br]SO_(4)`. To 1 lit of this solution, excess of `AgNO_(3)` is added. To the remaining solution of excen of `BaCl_(2)` is added. The amounts of precipitated salts, respectively, are

A

0.01 mol & 0.01 mol

B

0.01 mol & 0.02 mol

C

0.02 mol & 0.01 mol

D

0.02 mol & 0.02 mol

Text Solution

Verified by Experts

The correct Answer is:
D
Given that 2L solution contains 0.04 mol each of `[CO(NH_(3))_(6)SO_(4)]Br and [CO(NH_(3))_(5)Br]SO_(4)`. Therefore, the concentration is 0.02 mol `"lit"^(-1)`.
`underset("0.02 mol")([CO(NH_(3))_(5)SO_(4)]Br)underset("0.02 mol 0.02 mol")(rarrBr+[CO(NH_(4))_(5)SO_(4)]^(+))`
`underset("0.02 mol")([CO(NH_(3))_(5)Br]SO_(4))underset("0.02 mol ")(rarrSO_(4)^(-2))+underset("0.02 mol")([CO(NH_(3))_(5)Br]^(+2))`
`underset(("excess"))(Ag^(+))+underset((0.02))(Br^(-))rarrunderset(0.02)(AgBr)`
`underset(("excess"))(Ba^(+2))+underset((0.02))(SO_(4)^(-2))rarrunderset(0.02)(BaSO_(4))`
