of bromide to a strong solution of potassium hydroxide, evaporating the
potassium bromide and bromate to dryness, decomposing the bromate by
fusing the mixture with charcoal and purifying the crystallization.
PROPERTIES.--Colorless, or white, cubical crystals, or granules;
odorless and having a strong saline taste. Permanent in the air. Soluble
in about fifteen parts of water and in about one hundred and eighty
parts of alcohol.
