Re: Edexcel A2 Chemistry Unit 4 26/01/12 PMI 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..(Original post by This Honest)
Facer
I would have used it for AS if only I joined TSR ealier
CGP and the edexcel blue book from time to time.
3 books
How about you? -

Re: Edexcel A2 Chemistry Unit 4 26/01/12 PMI 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
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 -

Re: Edexcel A2 Chemistry Unit 4 26/01/12 PMI've been doing those loads of times so I'm comfortable with them(Original post by NutterFrutter)
I need to do some Rates of Reactions revision. Haven't looked at that in a while...
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

Finally I can do some questions which are worthwhile my time. Some of the questions in the edexcel revision guide are like WTF???

Re: Edexcel A2 Chemistry Unit 4 26/01/12 PMdo you mean the edexcel revision guide or the study guide??(Original post by Kasarna)

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

Re: Edexcel A2 Chemistry Unit 4 26/01/12 PMThere 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.(Original post by 11billi11)
Guys any thing to help with memorising all the organic reactions + conditions.. theres soo much and I can't seem to get it all in my head

Do you have an example question?
June 2010
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. -

Re: Edexcel A2 Chemistry Unit 4 26/01/12 PMWell, 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.(Original post by This Honest)

Re: Edexcel A2 Chemistry Unit 4 26/01/12 PMI see, so to get 12.5, you just divide 25cm^3 by 2(Original post by NutterFrutter)

why not the 30cm^3 -

Re: Edexcel A2 Chemistry Unit 4 26/01/12 PMOur boiling temperature is very high(Original post by James A)
i think we got some hydrogen bonding going on folkes.
in the....

im dichlorodifluoromethane because i can destoy the ozone, however i form permanent dipole dipole interactions with girls.Last edited by James A; 24-12-2011 at 19:33.
