    I thought the same thing but let it slide since how I wrote it is how it was stated in the Jan 10 mark scheme.

    I've looked into it and I can't find a single mention of the conventional representation of a hydrogen fuel cell anywhere in any text book or online source :confused: Don't know if it's an AQA mess up or we're missing something.
    Jan 10 markscheme says this:
    Pt|H2(g)|OH–(aq),H2O(l)||O2(g) |H2O(l),OH–(aq)|Pt ....

    Meh. I typed it out from one tab to another. I got H2O and O2 mixed up. At least we got it sorted...

    hey guys how would you work out weather smething is acting like a lewis acid .. would the ox state decrease
    Usually metal complex ions are lewis acids

    A lewis acid is an electron pair acceptor

    A few chapters are, the rest is application. But yes there is an awful lot of rote learning.

    I know just break them into small chunks, create a spider diagram for each TM adding reagent + product(formation of colours and their equation),i find it easy to memorise this way..

    I learnt my colours using 6 chunks. By remembering each metal ion as well as the 5/6 things that can be added to. Each time something is asked in a question I associate each reaction with a number 1 - 5/6 I find it quite easy to remember it that way. Also guys don't forget about [CuCl2]^2- and [CoCl4]^2- I think that's what the charges are...

    Cr gives you bit of headache, esp when it reacts with H2O2, H+, Zn/H2SO4, CO32- , excess of OH- and NH3 i guess the last two easy peasy

    Need to review all chapters + extra questions + past papers + bit of unit 1/2 synoptic. I doubt anything from unit 4 would come up...

    I keep forgetting chapter 15/16 though. They're so damn long.
