    For starters, purpose is not the right word. You mean aim.

    on is the wrong preposition, and so is with.

    Don't worry about whether your sentence is 'natural'. You should worry about saying it clearly and precisely. This is academic writing.

    What's all this stuff about Ginger?

    Do you mean with is not okay? I thought it is.

    three liquids with different purity atexposed to a temperature of -2 degrees Celsius for 2 hours.
    I think you need further information as is shown in red above to make the sentence meaningful.

    No, I mean of different purity.

    That's what I said—of not with.

    So what should the first preposition "on" be?

    The best choice is in, but to be honest, I'd rephrase the whole sentence.

    Re: The purpose of this experiment is to determine whether supercooling occurs on eac

    Oh, l think its an error message. I deleted it.

    The aim of this experiment is to determine whether supercooling occurs on each of three liquids of different purity at -2 degrees Celsius for 2 hours.

    Is it better to change '
    at -2 degrees Celsius for 2 hours' to 'exposed to a temperature of -2 degrees Celsius for 2 hours' ?
