Coordination Compounds 2 Question 41
43. Mixture $X=0.02$ mole of $\left[Co\left(NH _3\right) _5 SO _4\right] Br$ and $0.02$ mole of $\left[Co\left(NH _3\right) _5 Br\right] SO _4$ was prepared in $2 L$ of solution.
$1 L$ of mixture $X+$ excess $AgNO _3 \rightarrow Y$
$1 L$ of mixture $X+$ excess $BaCl _2 \rightarrow Z$
Number of moles of $Y$ and $Z$ are
(2003)
(a) $0.01, $ $0.01 $
(b) $0.02,$ $ 0.01$
(c) $0.01,$ $ 0.02$
(d) $0.02,$ $ 0.02$

Answer:
Correct Answer: 43. (a)
Solution:
- In $1 L$ solution, there will be $0.01$ mole of each $\left[Co\left(NH _3\right) _5 SO _4\right]$ $Br$ and $\left[Co\left(NH _3\right) _5 Br\right] SO _4$. Addition of excess of $AgNO _3$ will give $0.01$ mole of $AgBr$. Addition of excess of $BaCl _2$ will give $0.01$ mole of $BaSO _4$.
