Exactly, it's like WTF?? I can't think of any topics related to it either?? Perhaps oxidation states and all that but that'll be like 2 marks. I really don't know. They might ask about the halogens in water like what colour they'll be. I can't think of one questions they'd ask that would be more than 5 marks??

I totally think halogens- making and storage. I also think oxidation states, and maybe equilibrium.

I remember in the summer the questions on the article weren't too bad, nothing totally unexpected, so touch wood it wont be too bad again.

Like, florine is made in situ coz it's so reactive etc. It's in the revision guide.

Emailed my teacher, and this is what she said:
"From reading the advance notice article I would suggest questions could be
on the following:
ions in solution - hydrated ions
oxidation states
ionic equations
equilibrium reactions
halogenoalkanes - maybe drawing structure of THMs
a calculation related to the surface area of PAC
Remember they can't ask you anything you haven't already been revising for
the exam, the question should just be in the context of the article."
