Diffusion Experiment watch

    • Thread Starter

    Hi guys,
    I am going to do an experiment in my class about diffusion of food colour in agar jelly. This experiment is to check how concentration of food colour affects the distance travelled by it due to diffusion,.

    I can't understand what is meant by concentration in this experiment?

    Can anyone write a full experiment method so that I can check it with the method that I am going to use.

    I actually need to change concentration of food colour. Can u guys guide me how can I do this?

    Plz explain the experiment in logical step by step order. I need to finish my planning for this experiment tomorrow. Can u guys plz answer this question as soon as possible.

    Kind regards,

    i would have thought like 100% food colouring then mixing the food colouring and water together to make it weaker. it's probably too late for this now though, sorry.
