1.	Mixture of X=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 litre of solution. 1 litre of mixture X + excss of `AgNO_(3)to Y` 1 litre of mixture X + excss of `BgCI_(2)to Z` No. of moles of Y and Z are :A. `0.01, 0.01`B. `0.02, 0.01`C. `0.01, 0.02`D. `0.02, 0.02`
Answer» Correct Answer - a Concentration of ions in 1 litre of the solution after mixing will be reduced to half i.e. 0.01 mol. `underset((0.01"mol"))(Br^(-)+AgNO_(3))tounderset((0.01"mol"))(AgBr(Y))` `underset((0.01"mol"))(SO_(4)^(2-)+BaCI_(2))tounderset((0.01"mol"))(BaSO_(4)(Z))`
