    Good good I'm glad, yes I bet they are great we had an actual amazing (and interesting) group last year, it does not feel as daunting now I know somebody going through with me, I know what you mean I have not been revising intensely as I did last year trying to go with the calm relaxed approach this time. You ready?
    I'm just currently watching videos and slowly creating more brain cells in the process ( Hopefully it's enough). Are you ready?

    My revision guide says polydentate is more than two coordinate bonds formed, but isn't it two or more? (or more than one?)
    1 coordinate bond is monodentate, 2 coordinate bonds are Bidentate and then more than 2 is polydentate

    longer mark answsers,
    - TLC
    - Manganate ion titration practical
    -Colorimetry, although that came up last year u can never be too careful
    - recrystalization

    Do we need to know the reactions of Benzene ? like Nitration, fiedel crafts and all that jazz ? or is that f335 ?

    guys just a random question.

    Are we supposed to know how to name complex ions? (eg. hexaaquacopper(II) ion). The naming rules are just killing me.
    (Original post by EggsterminateMe)
    Yes and also the colour. I ahd to do it in one of the Exam papers.

    (Original post by suyoof123)
    Yes we are,

    Name the ligand/s first with the prefix for how many , then name the transition metal and depends if its negative or neutral/positive on what version of the name it will take along with the oxidation state.

    Okay I just read the Salters specification because I was pretty certain we don't need to be able to name Ligands, and under Steel Story part e) the specification quotes 'use systematic nomenclature to name and interpret the names of inorganic compounds [ie copper(II) sulfide, lead(II) nitrate(V), potassium manganate(VII), not complex ions]; '.
    Therefore we do not need to name them

    Sorry just a change to the wording of my previous post, yes we should be able to name Ligands (water, ammonia etc.) but not complex ions

    Yep it could come up since I've seen a past paper question asking for the name of a specific ether.

    From what I can tell, yes and no. In F332 we're supposed, so therefore we could get a question on it, but unlikely.

    For one of the questions they asked to draw an electrochemical cell for copper and iron. The copper electrode was copper metal but the iron was platinum. Why is that?

    There was a past paper question asking you to name an ether though so I wouldn't risk it. It's straightforward anyway.

    some help me on june 2012 5 b iii how is it a cordination number of 6 i know edta4- is a polydentate so how many bonds can it form? 6? why 6 why not 4?
    Coordination number is the number of dative covalent bonds
