    Do we need to know any experiments for this paper?
    Having an understanding of the MnO4- and the sodium thiosulphate titrations is useful I think, not sure about any other.

    Revision all night for me perhaps :bumps: :coma:

    I HOPE the examiners don't give us an essay-based paper. They suppose to test us on our chemistry knowledge. I HATE those longer answer questions (worth a whole grade etc.)

    Anyway, good luck with your exam tomorrow and any upcoming ones

    so guys just want to get one thing straight.
    in any redox titration question, if it asks you to find the concentration of an oxidising agent - will you always have to multiply by 10 as it has been diluted . because theres some questions ive been through that ask you to find the concentration of Cu2+ (the oxidising agent) but you don't know whether they asking you to find the diluted or undiluted concentration - so in the question i done, without mentioning diluted or undiluted, they multiplied by 10 anyway

    The most enjoyable question of the paper :sigh:
    Isn't it weird that what you hate the most always(or often) worth A LOT and can be a life-changing question --"

    Hi,

    I was wondering if others may be in the position where they feel they 'know' a sufficient amount, but are worried about this 'application' of science hinted at in the reports.

    Does anyone have any interesting predictions of how information may be woven into an 'apllication' question tommorow?

    (for instance the question on peroxide and hair in january)
    Yes, great shout bruv.
    That peroxide question was a Beatch, no?
    My fears were calmed a little when I re-read the question and found that they subtly give you hints, they kept talking about di sulphide bonds and showed a diagram of it, people can see it and hopefully apply it to the question.

    In terms of guessing what 'application' of science questions can appear?
    OCR allocated 46 marks out of 100 to sheep, hedgehogs, humus and ladybirds in teh bio paper yesterday, no telling what they'll do tomorrow!
    I'm gonna wikipedia on titanium hip implants and mothballs just in case

    It's a blue solution that turns yellow. In-between colour is green

    Green is just a mix of yellow and blue (original colour). Some people identify green as the final colour but its wrong.
