an alrightish quiz...although i believe there are more important aspects that you havent really touched upon like the colour changes and ppts formed... but good quiz anyway!:)

Great quiz!!!! Just one thing, on question 28 a halogen is an Oxidising agent and as as you go down the group oxidising power decreases, so it confused me a little, however I am doing a different course so I've probably learnt something different to you. 5 stars!! :D
