Mixture X = 0.02 mole of [Co (NH3)5 SO4] Br and 0.02 mole of [Co(NH3)5 Br] SO4 was prepared in 2L of solution. 1 L of mixture X + excess AgNO3-> Y 1 L of mixture X + excess BaCl2-> Z Number of moles of Y and Z are

Liters of the given mixture X contains 0.01 moles of each of the given complexes Also with 3 AgNO , only 3 5 4 [Co(NH ) SO ]Br reacts to give silver bromide as ppt. the reaction involved is 3 5 4 3 3 5 4 3 [Co(NH ) SO ]Br+AgNO [Co(NH ) SO ]NO +AgBr -> Similarly for the second reaction 4 BaSO will be precipitated. Hence, the correct answer is option (a)
