An aqueous solution of $$\text{CuSO}_4$$ called X is treated with certain reagents. Identify the incorrect statements

Addition of $$\text{NH}_4\text{OH}$$ to the aqueous solution of X develops green colour.

X is treated with $$\text{H}_2\text{S}$$ in acidic medium giving black precipitate soluble in hot aqueous KOH solution.

X on treatment with KI in weakly acidic medium gives white precipitate of $$\text{CuI}_2$$ liberating $$\text{I}_2$$ gas.

An aqueous solution of X when treated with $$\text{BaCl}_2$$ solution gives white precipitate.
