    Saima Hasnain Here are some notes i found a while ago, beware though these are for the previous spec so it contains some stuff we are not required to know and maybe missing bits and pieces too.

    Can anyone help me with this question please?
    (topix 3 redox)

    7. Write balanced equations for these redox reactions. State which element is oxidized and which is reduced in each example.
    a) Fe and Br2 to give FeBr3

    Overall equation: ………………….

    Element oxidized: …………………

    Element reduced: ………………

    I know that Fe has oxidized because its oxidation state went from 0 to 3+

    and that Br has been reduced as its oxidation state went from 0 to -1 (single atom)

    And for the half equations i got: Fe ---> Fe^3+ + 3e^- & 3e^- + 3Br ----> Br3^-

    same number of electrons in both half equations so it should make

    Fe + 3Br ----> Fe^3+ + Br3^-

    but the mark scheme says:2Fe(s) + 3Br2 (l) ----> 2FeBr3(s)

    Can someone explain what i did wrong? is it because i changed the Br2 into Br?
