A) \[Cu{{I}_{2}}+{{K}_{2}}S{{O}_{4}}\]
B) \[C{{u}_{2}}{{I}_{2}}+{{K}_{2}}S{{O}_{4}}\]
C) \[{{K}_{2}}S{{O}_{4}}+C{{u}_{2}}{{I}_{2}}+{{I}_{2}}\]
D) \[{{K}_{2}}S{{O}_{4}}+Cu{{I}_{2}}+{{I}_{2}}\]
Correct Answer: C
Solution :
\[2KI+CuS{{O}_{4}}\to \underset{\text{Unstable}}{\mathop{Cu{{I}_{2}}}}\,+{{K}_{2}}S{{O}_{4}}\] \[2Cu{{I}_{2}}\to C{{u}_{2}}{{I}_{2}}+{{I}_{2}}\] Hence, solution contains \[C{{u}_{2}}{{I}_{2}},{{I}_{2}}\] and \[{{K}_{2}}S{{O}_{4}}\].
