OCR qualitative chemistry practical 2015Watch
I have this practical next Friday
I've been told that it's on doing chemical test on solutions
have also been told to revise group 7
Anyone has any ideas on what this could be on from anyone that has already done it ?
Any sort of help would be much appreciated !!
Step 2 - look up the different chemical test on solutions. Some of them will contain the group 7 elements.
Any idea on how that comes into the coursework?
just simple advice would be much appreciated
