Im mainly struggling with questions 5 and 6, I really got no clue. Ive done questions 1 to 4 but not quite sure of the answers to the 2nd and 4th questions. I understand the concept of distillation and reflux but I don't know how to approach the question if you know what I mean? Anyway, my answers are: 1) because the conditions used were suitable for the oxidation of ethanol. The mixture of liquids in the distillate have different boiling points, so they can be seperated by distillation where one liquid evaporates before the other. 2) adding more acidified potassium dichromate. 3) temperature increases. 4) because distillation involves the heating of a liquid that has different substances with different boiling points and collecting their vapour. Thank you

5 - how hot do you need to get it?
6 - explain it in terms of IMF

I'm assuming you don't mean one third of the way around a circle?

So... why would a water bath not be the best bet?

Im sorry I don't understand??!
You are planning on heating something to 120 degree Celsius in a water bath that can go as hot as 100.

Pah.
