    Does anyone else find that in the text book the colours seem to change from page to page?
    Yup.

    Its impossible to answer exam papers as you give a colour, then aqa decide they wanted another :/

    This topic is rediculous... and i'm horridly under prepared for it

    is it possible to revise chem5 in a week?
    Yes. Get on with it!

    Im doing the exact same thing.

    My tip to you:
    Using those transition metal colour tables in the book... write out the equations on paper using coloured pencils so that you can visibly see the colour of the transition metal.

    Then write out the hexa aqua transition metals on paper, showing charges, naming its colour and wether its a ppt or solution.

    If it has no charge it's a ppt, if it has a charge its a solution.

    Then check it with the sheet you wrote out



    For example.

    [Fe(H2O)6]^2^+
    Green solution
    [Fe(H2O)6]^3^+
    Pink Solution.
    [Cr(H2O)6]^3^+
    Red Solution.
    Co(H2O)6]^2^+
    Pink Solution
    Cu(H2O6]^2^+
    Blue Solution
    (I memorised these since this morning.... I'm getting better! :P)

    Then start memorising what these turn into with different reagents (dilut NH3, Excess NH3, OH- etc)
    ..Which im doing now


    Good luck! And just put the effort in.

    I don't know why but i find this the easiest part of Chem 5, as its easy marks. For me some of the redox equilibria can be quite hard

    For the portable batteries (Ni/Cd), which is at the positive electrode and which is at the negative electrode?

    yes definately agree with u there
    i find the colours the easiest marks if u learn em u get the marks i hate redox

    i have a better way to revise all the colours
    what u do is u learn them in the order of the periodic table
    eg fe2+ aq then co2+aq then Cu2+aq that helps me to remember them better
    then cr3+ ,fe3+ and then al3+
    with oh- and nh3 h20 and cl- and carbonate exces and stuff
    helped me but i dont knw bout anyone else
    hope it does though

    Isn't that Chem 2? I don't think we need to know it, the only synoptic stuff in chem5 is trends in periodic table e.g electronegativity afaik.
