    BROWN! Well when answering chemistry papers, i always say "Bromine water changes from brown to colourless" (thats the test for a C=C double bond by the way )
    but yeah I usuallly say brown, spose orange brown is right!

    Depends on concentration! It could be colourless, or it could be the same colour as pure bromine!

    surely the colour depends on the concentration of bromine in the aqueous solution, hence the different colour, though i usually see bromine water as orange-ish.

    I think that's bromine rather than bromine water.

    No, bromine is so dark in its pure form that it's almost black :yep:

    what is defined as pure bromine anyway? gaseous/liquid? How concentrated?

    Pure is pure, i.e. it doesn't have a concentration (a term usually reserved for solutions).

    It is a liquid element at room temperature.

    If you wish to be pedantic its 'concentration' in moles per litre would be equal to its density in g/cm3 multiplied by 1000 and divided by its relative mass.

    That, at least, would give you a value of moles per litre.
