Mixture X=0.02mol of [Co(NH3)5SO4]Br and 0.02mol of [Co(NH3)5Br]SO4 was prepared in 2 litre of solution. 1 litre of mixture X+ excess AgNO3→Y 1 litre of mixture X + excess BaCl2→Z
Number of moles of Y and Z are
A
0.01,0.01

Solution
The correct option is A0.01,0.01 1.0 L of mixture X contain 0.01 mole of each [Co(NH3)5SO4]Br and [Co(NH3)5Br]SO4
Also, with AgNO3, only [Co(NH3)5SO4]Br reacts to give AgBr precipitate as: [Co(NH3)5SO4]Br0.01mol+AgNO3excess→[Co(NH3)5SO4]NO3+AgBr0.01mol
Similarly, in the second reaction BaSO4 will be precipitated [Co(NH3)5Br]SO40.01mol+BaCl2excess→[Co(NH3)5SO4]Cl2+BaSO40.01mol
Option (a) is correct.
