$Cu^{2+}$ oxidizes iodide to iodine

(B) $Cu^{2+}$ is a strong oxidizing agent and $I^-$ is a strong reducing agent. When $Cu^{2+}$ reacts with $I^-$,$Cu^{2+}$ oxidizes $I^-$ to $I_2$ and itself gets reduced to $Cu^+$. The reaction is: $2Cu^{2+} + 4I^- \rightarrow 2CuI + I_2$. Therefore,$CuI_2$ is unstable and does not exist.
