Answer 2

Answer:

(b) colourless solution of zinc sulphate is formed

Explanation:

Zinc is more reactive than copper. So it displaces copper from its aqueous salt solution to form a colorless solution of zinc sulphate. The reaction involved can be written as

Zn(s) + CuSO₄(aq) → ZnSO₄(aq) + Cu(s)
