    Paper 5 Tips !! :)

    Yes, that's the method I'm familiar with also. That's what makes sense. ---> I haven't thought this through but you could also calculate mass of dissolved by the excess as all you have to do is subtract?

    I highly suggest you take time to make a chemP4 thread so we can use that! Like xhizors made separate for P5 it'll be much easier? Tag us all?

    Chemistry: Post your doubts here!

    Decided to read the paper: I don't think that method is applied here. Here, you'd calculate number of moles needed in 250 cm3 to make 1.39moldm-3 Using the unity method you should be able to do that. ---> then use moles to find mass needed. ----> NOW what you do is dissolve the solid mass...

    For saturated solutions usually the following method is used: -Add fixed masses (eg 2g) to a fixed volume of water (eg) 100cm3 -Add one sample of fixed mass, stir and see if any crystals (undies solved) appear. -If they do, don't add any further mass and proceed to step (2) -If they don't, add...

    BEST way is to just go through papers 2007-2012 and if you don't have time -just 2012-2010 is sufficient! -Mark problem areas and review those from the book ALSO please make a separate Chem P4 thread and we can start discussions there as well!

    Paper 5 Tips !! :)

    You're lucky I just reviewed that! :) -for the (I) part we just use a total fixed volume of H202 + H20 (I used 100cm3) -And vary the volumes of each to vary concentration - %of sol in overall = %of original concentration !! -Just to get you started: -ex: 40cm3 H202 + 60cm3 H20 -What's the...

    Hey! My sister is giving P2 tommorow and she's fully prepped just going through final revision! She has a problem with ON 2010/ 22 with Q6 Part b could you give her an explanation of the formula used in the marking scheme?

    It does make sense! But sometimes it says like reading taken at too high a temp (as ind) and the error would be due to not letting apparatus cool down ?

    I did as below: -1 column mass of solid (D-C) in g -2nd column mass of water (C-B) in g -3rd column solubility per 100g (E*100) /F The last parts logic Is as follows: -Since solubility is to be given in g of solid per 100g of water, You divide 100 by the mass of water and that given you...
