For the 400 or so people that do it
How do you think you went
and what was with that Vanadium oxidation state question where you had to find a graph and justify it
Wtf was that!

The 7 marker was a gift though

Vanadium was one of the ones I managed to get...you just show that blue and red aren't absorbed (draw a continuous line absorption spectrum with percentage absorption) and that explains the purple colour. It's like drawing the opposite of a reflectance spectrum.

The one I struggled with was the permanganate prac...didn't remember the method at all :S

Mmm, also the first question was like the most complicated!

i struggled on the option;;;
i spent so much more time studying the option recently than the core, but the questions killed me.
i had never seen a graph like that, and didnt know how to 'sketch' the other one...


i am so so worried
