    I got an A for F334 and was told that this exam is harder contrary to what people seem to saying here which is good. It's supposedly harder due to questions being much more focused on applying your knowledge rather than recalling, but i'll know more when I've done more papers; i've just done the specimen and it was pretty hard because I havn't gone through the revision guide or anything yet, but to be honest that's because I find doing past papers and using the mark schemes a more direct way of learning the material.

    I will agree with others after doing this first paper that it seems a lot more synoptic than F334 which I suppose is a good thing :P

    I'm retaking F331 in june as well just to try and get a bit more security :P

    I've looked at the specimin, admitadely I couldnt do all the questions because we've not as of yet finished learning everything, however most of it looked fairly straight forward, I mean there were a few questions where I wasn't sure where I'd get full marks from, but other than that it looked okay, partly because there were a lot of easy marks (synoptic).

    I'm pretty scared about this exam. I need to learn all the stuff. Would 6 weeks be enough to get from a D/C to an A/A*? I think I left it too late.

    I'd say a week of solid revision is enough to learn everything.

    Ok. Including other subjects? Or straight revision for a week?

    got 4 exams in the first half of exams, completely ready for 1, nearly ready for another, and the rest i'm planning on scraping an A which i usually do.
    I think I'm overeacting, now i've started test papers it doesn't seem as bad anymore.

    yeah, it's all about doing past papers to get familiar with the material and how you're supposed to answer.

    what have people been finding the most difficult about the f335 content?

    Chromophores, the long questions, and gas liquid chromatography.

    Help with this question

    Addition of a small amount of ammonia solution to [Cu(H20)6]2+ solution forms a pale blue precipitate. Write an ionic equation for this precipitation reaction.

    The mark scheme says
    Cu2+ + 2OH- -> Cu(OH)2

    but i dont understand where the OH- comes from

    sorry if the equations are confusing, I dont know how to do subscript and superscript and all that stuff.
    thanks
    (its f334 btw but this thread seems more alive than the f334 one )

    Subscribing!
    So far, I'm finding entropy a tad difficult to grasp, but hopefully with past papers and revision I'll get my head around it.

    How much of F335 (the exam) is synoptic and how much is new stuff? I mean is it a 50:50 split or what?
    Seems like most of it is synoptic - its good with being on Salters that there isn't really that much new stuff. Most of it does seem to just be slightly harder forms of stuff we've seen before. Apart from really obvious new bits like entropy calculations.

    If I remember correctly, its because in ammonia SOLUTION, you have NH3 and H2O. Because the ammonia is a base, it will accept a H+ from the water, so leaving you with OH-.

    Yeah, that's right. Ammonia solution (Ammonium Hydroxide) has NH4+ and OH- ions in equilibrium:

    NH3 + H2O <--> NH4+ + OH?

    (Sadly, TSR doesn't have an equilibrium symbol, so I went with a dodgy arrow)

    Edit: That should be a '-' not a '?'... :|
