    Same I just finished with periodicity, I always forget the acid base titrations Right, by 1 I'm gonna get through the last two chaps AND the table..or so I say lol..then read over my notes and the new papers then sleep by ummm...half 2? :/ What time will you be getting up?

    ohh and I'm yet to go through mod1 :mad:

    :mad2: haha I really like this
    Sorry to butt in on your conversation, but I'm a bit concerned, what is mod1?

    Cheers Yeh I sort of cheated and just learnt the ones that change lol, but the colour really confuse me..I keep forgetting them, I think I'll try doing your method and see if it works..hopefully just hopefully it will.. ;D Also, for Al with xs NaOH, is it [Al(OH)4(H20)2]- or something else? The mark scheme say something different and I have this written down :/ What work are you doing now? Reckon it'll all be done by 1??
    It's Al(OH)4-, I think for the same reasons you can only get 4 chloride ions around an ion.

    Do we need to know CoCl4 FeCl4 and CuCl4 Colours?
    I think just that CuCl4 is yellow.

    Hey guys! I'm about to go to bed but I though I'd share a bit of a silly way to remember some of the colours

    Well, it's the M3+ ones anyway

    Most of the chromium ions are greenium! Apart from the hexaaqua one which is Cr-uby and the XS ammonia one is purple but I have no way of remembering that one :L
    Aluminium is Al, a boring white man who's colourless when he goes swimming.
    And just like JD and Turk off Scrubs, Al needs a brown best friend and that is all of the Fe3+ compounds (apart from the hexaaqua one)

    Lol, I know, it's awful. It might stick in your heads though

    Good luck everyone, fingers crossed for a nice paper!

    I am gonna try to get up at 6, because I know for a fact that I'll probably have forgotten what I learn the last 2 days!!
    I wanna read over synoptic but I don't have time! I should know unit 2 as I retook it but I don't lol haha. :p:

    thank you can you please tell me what the overall equation will be?

    I got felt tip pens and copied the tables in the book in the colours it said. Ended up with a nice colourful table which I can visualise in the exam and at least get the colours right, if I screw up the equations.

    Your way is catchy though!

    Formation of coloured ions - appreciate that this absorption of visible light is used in spectrometry to determine the conc of coloured ion.

    So we don't really need to know the method or anything in detail do we? :/

    I think we have to know E=hv to work out the difference in energy levels.

    I am so so so mega scared for this exam it's UNREAL =(

    I know my stuff. I think. I've spent two days going over and over my notes and reams of past paper questions plus mark schemes but I trust AQA about as much as a noble gas reacts... urghh

    I need to sleep otherwise I'm gonna make silly mistakes tomorrow as usual. But i haven't done any of the actual past papers. (stupid I know but I've done loads of practice questions) should I do the 3 papers or go to sleep? someone decide for me?

    Im assuming the past paper questions ARE from past papers, so theyre equivelant I guess...

    born haber isnt too bad, you just remember to draw it clockwise, and they will only ask you for lattice enthalpies, so remember, formation, atmomisation( usually non metal first), ionisation, affinity then dissociation or formation lattice enthallpy

    they're from legacy/old spec papers from the relevant topics...
