Q. Complex salt can be made by the combination of $\left\lbrack Co^{III}\left( NH_{3} \right)_{5}Cl \right\rbrack^{x}$ with
A) $Cl^{-}$
B) $2Cl^{-}$
C) ${PO}_{4}^{3 -}$
D) 2$K^{+}$
Explanation
(b)
$\left\lbrack Co\left( NH_{3} \right)_{5}Cl \right\rbrack^{2 +} + 2Cl^{-} \longrightarrow \left\lbrack Co\left( NH_{3} \right)_{5}Cl \right\rbrack Cl_{2}$
