Bromate synonyms

Barium bromate, Ba(Br03)2, can be prepared by the action of excess of bromine on barytawater, or by decomposing a boiling aqueous solution of loo parts of potassium bromate with a similar solution of 74 parts of crystallized barium chloride.

Stas, in his stoichiometric researches, prepared chemically pure bromine from potassium bromide, by converting it into the bromate which was purified by repeated crystallization.

By heating the bromate it was partially converted into the bromide, and the resulting mixture was distilled with sulphuric acid.

Some reactions, which are only possible by the aid of nascent bromine, are carried out by using solutions of sodium bromide and bromate, with the amount of sulphuric acid calculated according to the equation 5NaBr NaBr03-1-6H2S04= 6NaHSO 4 3H 2 O 6Br.

Further, certain cubic crystals, such as sodium chlorate and bromate, and also some liquids and even vapours, rotate the plane of polarization of the light that traverses them, whatever may be the direction of the stream.
