    lol yeah xD

    - websites/youtube videos for learning the practical techniques mentioned in the specification like recrystallisation/filtration etc. (I have never done any experiments in chemistry, so I need to watch videos, lol)
    - be able to draw apparatus
    - unit 4 topic 1 (A2 book) for reaction kinetics experiments (in case they ask again)
    - knowing all reactions in unit 4 and 5 (and 1,2) is a good idea
    - unit 5 transition metals / colours / hydroxide precipitates
    - mass spectrometer/IR/NMR general knowledge from AS/A2 books
    - past papers
    - reading older unit 6b topics here on tsr
    - chemguide.co.uk

    International Specification for Unit 3 & 6

    Is it alright for us to discuss the paper now? Has the time restriction been over? By the way, I will be sitting for the international written test for physics unit 6 too! Just noticed you have open a thread for it, see you there after our exam How did you find the paper by the way?

    Also feel free to post there before the exam.


    For Edexcel: morning exams may not be discussed until 12:00 midnight (UK time) and afternoon exams until 4:30 AM (UK time). There are different rules in place for Edexcel ICT exams as these can be sat over several weeks.

    so only 19 minutes left, lol
    Tell me first what do you think? (after 19mins) xD

    oh okay sure. XD
    Only less than 4 days left for preparation for physics 6. Gosh.
    Didnt really study enough for it.

    I am in europe (of course not UK), self teaching at home (never attended a school/college).

    As far as I know, you guys now have to do experiments at school, so what did you guys do, or better I should ask 'did you guys do anything' lol

    Yea we do carry out practicals for all the science subjects. Our school labs are quite well-equipped.

    The paper was okay, of moderate difficulty I suppose.

    For the first question, I concluded straight it was Fe2+ by looking at the pale green appearance. In fact that's what I wrote for the inference.
    My answers for question 1 in the correct sequence, briefly:

    The cation present is Fe2+
    The reaction is deprotonation, casuing the pH 6 in water.
    NaOH as a base.
    Fe(OH)2
    The reaction which occured was oxidation.
    Fe(OH)3
    The hydroxide is NOT amphoteric.
    BaSO4 is the white precipitate.
    Compound A is FeSO4

    Any numbers/figures that you can recall from your answers?

    I got the percentage yield to be 57% in 2 sf.

    And I found the concentration of sodium dichromate to be 8.29X10^-3 mol dm-3
