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

Explanation

`I^(-)` ion reduces `Cu^(2+)` ion to `Cu^(+)` ion. The chemical equation for the reaction is :
`2Cu^(2+)(aq)+4I^(-)(aq) to underset("(White ppt.)") underset("Copper (I) iodide")(Cu_(2)I_(2))+I_(2)`
