I totally agree, I was waiting for a question on chelating lignads! but it never came. The energy level diagram question was a bit left field and that Ancient pigments essay!randhi said:Yeh i have to agree, i was expecting something really tricky like on chelates, models or why complex ions get their colour but this was relatively okay. although i did stuff up the Sodium one, well the first part anyhow so two marks down the drain
That wasn't too bad for me, because our school had a research task on chem of art and that question almost word for word came up in the research task so that helped in terms of being able to remember that stuff... but other than that I wasn't too worried except how the hell do u award 4 marks for explaining why transition metals have multiple oxidation states, isn't that really a 2 marker because the Bohr model is so much more in depth for the same amount of marks.S_Kaye said:good
except that 7 marker for egyptian pigments. what the fuck?
