Mixture X= 0.02 mole 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 + excess AgNO_(3) to Y 1 litre of mixture X + excess of BaCl_(2) to Z Number of moles of Y and Z are

Answer»

0.01, 0.01
0.02, 0.01
0.01, 0.02
0.02, 0.02

Solution :Mixture X will CONTAIN 0.02 mol `Br^(-)`IONS and 0.02 mol `SO_(4)^(2-)` iojnsin 2 L solution. Hence 1 L of mixture X will contain 0.01 mol `Br^(-)` and 0.01 mol `SO_(4)^(2-)`ions. With excess of `AgNO_(3)` , 0.01 mol of AgBr i.e. Y is formed. With excess of `BaCl_(2)` , 0.01 mol of `BaSO_(4)`i.e. Z is formed.
