I've just started the 2 year iGCSE course and I've already been set a ton of homework so the question goes like this:
Design a simple experiment, giving full practical details, which would let you compare the rates at which two strongly coloured solutions diffused through water. At each stage, think about exactly what problems might arise in carrying out the experiment, and say clearly how you would overcome them.
It's to do with Chromatography but there was no discussion of comparing rates.
I don't want a full answer I want a short answer that I can make into a long answer myself.
Just need help on this one thing, thanks guys
