[Hathesque]

Bromide solution, HCl, chloramine-t and chloroform are mixed together. There are two separate layers and the one with chloroform is brownish(there's also a cation in the solution so the colour might be a tad off).

The question is what exactly happens during the reaction? Why does the chloroform layer change colour?

What I've come up with so far: bromide gets oxidised and there'll be bromine molecules. I assume that somehow affects the colour, maybe by bromine dissolving in chloroform?

Did you see pure bromine? If not, take a look at the English Wikipedia. There is a quite realistic photograph of a bromine sample.
Now imagine the solution diluted more than 1000 times.
