    \[KI\]and\[CuS{{O}_{4}}\]solution when mixed, give:

    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 :

                     \[2KI+CuS{{O}_{4}}\xrightarrow{{}}\underset{unstable}{\mathop{Cu{{I}_{2}}+}}\,{{K}_{2}}S{{O}_{4}}\] \[2Cu{{l}_{2}}\xrightarrow{{}}C{{u}_{2}}{{I}_{2}}+{{I}_{2}}\] Hence, solution contains\[2Cu{{I}_{2}},{{I}_{2}}\]and\[{{K}_{2}}S{{O}_{4}}\].
