OCR qualitative chemistry practical 2015

Hi,
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 !!
:smile:

Step 1 - look up group 7 and note down all the elements in that group.
Step 2 - look up the different chemical test on solutions. Some of them will contain the group 7 elements.
