    You're looking for a substance that lowers the freezing temperature of water when added.

    I know.

    How would I work out which substance it specifically refers to.

    Thanks

    I know its something to do with Netwon's visible spectrum I get E, B,A,G,D but I don't get F & C. Also, some some colours of the compounds don't match. I don't know what am i doing wrong.

    Well I think the colours are the molecules in their states at room temperature, so I think they should all match.
    You just order the colour like the spectrum, and if you don't know the 2 of them ten sub them into the colours left over and swap them until it works

    Thank you for your help.
    But I'm getting B and D as the same colours. Am I going right?

    Well B & D are similar, but B is probably correct if you've got the colour of the solution (it's quite well known for its colour)
