Excess of KI reacts with CuSO₄ solution and then Na₂S₂O₃ solution is added to it. Which of the statements is incorrect for this reaction?

Accepted Answer

4 \overset{- 1}{K I} + 2 C u S O_{4} \to \overset{0}{I_{2}} + C u_{2} I_{2} + 2 K_{2} S O_{4}

\overset{0}{I_{2}} + 2 N a_{2} \overset{2 +}{S_{2}} O_{3} \to N a_{2} \overset{+ 2.5}{S_{4}} O_{6} + \overset{- 1}{2 N a I}

In this

C u I_{2}

is not formed
