Hi everyone.
So this is a question, I cannot find answer to and it is about one of the reaction I carried out during my last practical classes.
So this is reaction of Br- with KMnO4 . My solution changed colour to bright yellow. I was wondering whether it is a colour of one of the compounds of Mn or is it the colour of Br2 in the solution. I've searched for different Mn compounds but I am not able to find anything which is bright yellow.
Also, the Br- solution turned yellow after adding conc. H2SO4 so I assume it must be Br2 but I'm not sure.
Could you advise me on this?
Cheers!
