Solution

The correct option is C $0.01, 0.01$
1.0 L of mixture X contain 0.01 mole of each $[(C o (N H_{3})_{5} S O_{4}] B r$ an $[C o (N H_{3})_{5} B r] S O_{4}$ .

Also, with $A g N O_{3}$ , only $[(C o (N H_{3})_{5} S O_{4})] B r$ reacts to give $A g B r$ precipitate as

$[C o (N H 3)_{5} S O_{4}] B r + A g N O_{3} \to [C o (N H_{3})_{5} S O_{4}] N O_{3} + A g B r$ (0.01 mol)

0.01 mol excess

Similarly, in the second reaction, $B a S O_{4}$ (Z) will be precipitated.

Hence option C is correct.
