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?
