F334 (14/01/2013 1:30PM) - Salters Chemistry (Chemistry of Materials) Revision Thread

my school has only had us do papers from 2009 upwards, where can i get the stuff from before that?

In some of the legacy papers there are irrelevant topics, such as NMR and Equilibrium constants; so just ignore them. Good luck :smile:

Hey guys, I've made some revision PowerPoints for myself and thought I'd put them up here. Haven't finished SS and TL yet but also have some for OCR A2 Biology F214 (11/01/13) if anyone's interested.

Here you go guys:
Mark scheme F334 June 2012 :smile:

Thank you! Thank you! Thank you!
It hard to know where you've gone wrong without a markscheme

btw I gave you a positive rating :smile:

i must say that 2012 papers contain some very strange and hard questions !!! :s-smilie:

Which ones? I found the questions broadly average tbh. Remember, the chemistry is always the same regardless. :smile:

Does anyone else get really frustrated when the mark scheme is different every time for drug testing?!
It changes every time for why transition metals are good catalysts as well

I havent noticed much variation in the drug testing questions.
That's because it varies depending on whether it's homogeneous or heterogeneous.

If I was to retake a retake, would they take that result or would they take the best result out of the 3? (hopefully it won't come to that)
I'm only asking, because biology take the result of the second retake, but they are different exam boards.

They always take the best result regardless.

Abit stuck on the oxidation questions when H+ becomes involved.
For example when MnO4- + 8H+ + 5e- > Mn2+ + 4H2O

The hydrogens are for the H in h2o i think? But where do the electrons come from?

Mn is +7 in MnO4- so 5 electrons are needed to make Mn2+

Thanks!
So when Mn is +7 it will always be 5 elecs?
And in the moles question youll have to times by 5?

Dreading this exam :/

I just did the Jan 11 paper and got 70/90 - the grade boundaries said 63/90 for an A does anyone know what an A* is??

Also can anyone explain why the complex ion [Fe(H2O)6)3+ is yellow?

Thank you!

68 ish. If you're talking about questions with them in solution you should talk about how it transmits yellow wavelengths of light whilst absorbing complementary wavelengths.

Woo! Thank you so that explains why but the question asked what colour it was? So do I just have to know that the Fe irons are that colour?

Does anyone have the mark scheme for the June 2010 legacy paper? Its from the old spec, 2849/01

The water Ligands cause the 3d orbitals in Fe(|||) to split, some orbitals become lower in energy as some become higher, this creates an energy gap between the orbitals. Light is absorbed through this gap, and the size of the gap corresponds to the wavelength of light that's absorbed (in this case it's violet). The colour we see in the complex ion is the complimentary colour to that absorbed ((yellow is complimentary to violet)... hope this helps :smile:
