Copper sulphate solution on treatment with excess of KI gives whitish precipitate. The precipitate is-

Question 1

(a) CuI2

(b) Cu2I2

(c) Cu2SO4

(d) I2

Question 2

Correct Answer is: (a) CuI2

The whiteish precipitate is copper iodide. The reaction is as follows:

CuSO4 + 2KI → CuI2 + K2SO4.

Here all the products and reactants are in aqueous state except CuI2 which is the insoluble solid and is therefore the precipitate.
