The bromate anion, BrO, is a bromine-based oxoanion. A bromate is a chemical compound that contains this ion. Examples of bromates include sodium bromate, , and potassium bromate, .
Bromates are formed many different ways in municipal drinking water. The most common is the reaction of ozone and bromide:
Br + → BrOElectrochemical processes, such as electrolysis of brine without a membrane operating to form hypochlorite, will also produce bromate when bromide ion is present in the brine solution.
Photoactivation (sunlight exposure) will encourage liquid or gaseous bromine to generate bromate in bromide-containing water.
In laboratories bromates can be synthesized by dissolving in a concentrated solution of potassium hydroxide (KOH). The following reactions will take place (via the intermediate creation of hypobromite):
+ 2 OH → Br + BrO +
3 BrO → BrO + 2 BrUsage examples of "bromate".
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.
When he mixed citric acid and bromate ions in a solution of sulfuric acid in the presence of a cerium catalyst, he observed to his astonishment that the mixture became yellow, then faded to colorlessness after about a minute, then returned to yellow a minute later, then became colorless again, and continued to oscillate dozens of times before finally reaching equilibrium after about an hour.
Its salts are known as bromates, and are as a general rule difficultly soluble in water, and decomposed by heat, with evolution of oxygen.
It was a semi-liquid preparation, bromine, used extensively to form bromides and bromates and as such the two cylinders containing it were labeled in Martian characters.
Schlink agreed with Kallet's observations about the additives in ground meat and also questioned the use of potassium bromate in the production of white-flour buns.
Tracing the circuits of the flour-stream blender to allow for manual operation seemed straightforward enough, but I forgot about the sample analyzer with its additive-injection unit for quality control Bypass that and you get raw stuff with a funny color and unpredictable properties that brings the bakers screaming- Try to inject the additives manually and you end up with half-poisonous crap contaminated with benzoyl peroxide and potassium bromate and Tana knows what else.
