A mixture `x` containing 0.02 mol of `[Co(NH_(3))_(5) SO_(4)]Br` and 0.02 mol of `[Co(NH_(3))_(5)Br]SO_(4)` was prepared in `2 L` of solution.
`1 L` of mixture `X + ` excess `AgNO_(3) rarr Y`
`1 L` of mixture `X +` excess `BaCl_(2) rarr Z`
The number of moles of `Y` and `Z` are

Options

A. (a)0.01, 0.01
B. (b)0.02, 0.01
C. (c )0.01, 0.02
D. (d)0.02, 0.02

Answer

A

Explanation

A mixture `X` containing `0.02 mol` of `[Co(NH_(3))_(5)SO_(4)]Br` and `0.02 mol` of `[CO(NH_(3))_(5)Br]SO_(4)` was prepared in `2 L` of solution. This means `1 L` of the mixture contains `0.01 mol` of `[Co(NH_(3))_(5)SO_(4)]Br 0.01 mol` of `[Co(NH_(3))_(5)Br]SO_(4)`.
`1 "L of mixture X + excess AgNO"_(3) rarr 0.01 mol AgBr`
`1 "L of mixture X + exess BaCl"_(2) rarr 0.01 "mol BaSO"_(4)`
This is according to the following reactions taking place:
`[co(NH_(3))_(5)SO_(4)]Br+AgNO_(3) rarr [Co(NH_(3))_(5)SO_(4)]NO_(3)+AgBrdownarrow`
`[Co(NH_(3))_(5)Br]SO_(4)+BaCl_(2) rarr [Co(NH_(3))_(5)Br]Cl_(2)+BaSO_(4)downarrow`
