Qualitative A2 OCR help

Hey, I have the qualitative assesment this week, the title is. 'You will prepare a complex of copper. You will carry out some tests with compunds of copper'

Is there any advice anyone could give me for this? What possible tests could I carry out at A2, and what different observations could they ask me for. So far we have reacted a copper solution(pale blue) with sodium hydroxide and a brown precipitate formed? What possible colours could copper turn?

OP

BUMP

did you do it and how did you find it, mine is tommorow, any advice or help?
i flopped the benzoic evaluative last week so i still need to do another evaluative. anyways good luck on you practicals if you havn't done them already. :smile:
