    Facer
    I would have used it for AS if only I joined TSR ealier :sigh:
    CGP and the edexcel blue book from time to time.

    3 books :eek:
    How about you?
    I have all 3 too! But the george facer one waffles a lot .. and sometimes it gives too much detail. I just used it for around 3 chapters..

    I also use the George Facer book....had it last year though I felt as if my teacher was trying to punish me so i never used it :banghead:

    However we weren't given the black book this year so had to use the facer book and soon I grew to love it....does everything in the specification and more.

    Wish i knew where i could find the god-damn answers to the questions though thats the only problem

    I've been doing those loads of times so I'm comfortable with them

    I think I need to work on drawing the ph graph for bases and acids in the context of the question.
    Also, I need to work on nmr, HPLC, GC- i detest those :sigh:

    do you mean the edexcel revision guide or the study guide??

    the study guide waffles too much but the end of unit questions for the revision guide are similar to those in the real exam

    There isn't much on organic in Unit 4 tbh. Just go through the organic chapter making notes on the reactions (no additional info) and just go over it all until you remember it. Then practice with past papers.

    v) On the axes below, sketch the titration curve for this reaction when 30 cm^3 of the NaOH is added to 25cm^3 of the vinegar solution.

    Well, you know a strong base is being added to a weak acid. You should know the general shape for all 4 types of titration curves. You have already worked out the pH of the acid, so you have your starting point. You know that there is 5cm^3 more of the base being added so it's going to finish strongly alkaline (high pH). The equivalence point is at 12.5cm^3 so that is where you draw the vertical part of the graph.

    I see, so to get 12.5, you just divide 25cm^3 by 2
    why not the 30cm^3

    xD, but you two can form dimers xD

    im dichlorodifluoromethane because i can destoy the ozone, however i form permanent dipole dipole interactions with girls.
