Why does the colour of copper sulphate solution change when an iron nail is dipped in it

Nov 30, 2021

Blue colour of the copper sulphate solution changes into green colour & then iron nail acquires a brownish look. This is because that iron is more reactive than copper. The following chemical reaction takes place in this activity. Fe+CuSO 4. . →FeSO 4. . +Cu. In this reaction, iron displaces copper from CuSO 4
