When `Cu^(2+)` ion is treated with KI, a white precipitate is formed. Explain the reaction with the help of chemical equation.

Explanation

When `Cu^(2+)` ion is treated with KI, it produces `Cu_(2)I_(2)` white precipitate in the final product.
`2Cu^(2+)+4I^(-)rarrunderset(("White ppt."))(Cu_(2)I_(2))+I_(2)`
(In this reaction, `CuI_(2)` is formed which being unstable, dissociates into `Cu_(2)I_(2)` and `I_(2)`).
