When Cu2+ ion is treated with KI, a white precipitate is formed. Explain the reaction with the help of chemical equation.

NEETprep Answer: When Cu2+ion is treated with KI it produces Cu2I2 white precipitate in the final product.
 
                2Cu2++4I-Cu2I2+I2
(Whiteppt.)
  In this reaction, CuL2 is formesd which being unstable, dissociates into Cu2I2andI2)
