    From the reaction, 2FeCl2(aq) + Cl2(g) → 2FeCl3(aq)

    1. Fe2+ ions are oxidised to Fe3+, not reduced.

    2. Chlorine acts as a oxidising agent because chlorine undergoes reduction from oxidation no. 0 to -1, Fe2+ ions are oxidised to Fe3+.

    3. Fe2+ ions each lose an electron.

    4. Cl 2 molecules are reduced to Cl– ions.

    Ans: D 3 and 4
