    why do you have to work out concentration, didnt they give you the concentrations of the acid
    They gave you concentration of it in that volume (200 or 800 cm3). When you add them together, the new volume is 1000cm3 therefore concentration changes.

    i used correct examples, an electrode potential less than Cr for oxidising agent and greater than Cr for reducing agent
    that's exactly what I did, all of those reactions are feasible, why wouldn't they be?

    Nope bexause cr2+ would be feasible for all the reactions but you're strictly looking at cr3+

    The highest the boundary has ever been (for this spec) is 71 for a B. I think this year's paper was harder than that one. I'd say about 65-ish for a B

    Do you mean ChemistryALevel? He predicted 50/60 for an A in F324 and 77/100 for an A in F325. Personally I think the F324 boundary will be a bit lower, but he's probably about right for F325.

    47-48 for an A I'm absolutely sure it won't go higher than that; although it was an easy paper it was even easier to make ridiculously stupid mistakes

    F324: 51 for an A, 55 for an A*.
    F325: 79 for an A, 87 for an A*.
    Practicals: Up by one mark from 36 to 37/40 for an A. On the bright side, this means that you now get full UMS if you only got 39/40 raw marks. (yay me!)

    not the nicest grade boundaries The practical has really screwed me over I think. Big sarcastic clap for those of you insisting F325 would have a 75/74 mark grade boundary for an A (I Knew it wouldn't).
