Predict: (a) Will iron displace copper from CuSO₄? (b) Will copper displace zinc from ZnSO₄? Step 1: Series: ... Zn > Fe > ... > Cu ... (Fe is above Cu; Cu is below Zn). Step 2: (a) Fe is more reactive than Cu → Fe + CuSO₄ → FeSO₄ + Cu. Yes, blue solution fades, copper deposits. Step 3: (b) Cu is less reactive than Zn → no reaction. Rule: a metal displaces only metals below it in the series.
