Aqueous sodium bicarbonate was used to wash the crude

Nov 30, 2009  The aqueuos phase will become very acidic (phosphoric acid and HBr) and some of this acidity transfers to the aqueous phase. The washing with bicarbonate will then remove the acid from the aqueous phase. It will also remove traces of bromine (slight yellow colour) in the product as well. Bromine can be a by-product of the reaction.
