Summary: Bromide is the anion of bromine, element 35 on the periodic table. Bromide is the conjugate base of hydrobromic acid. Bromide commonly forms compounds with cations such as sodium and potassium. It may be found in the environment associated with sodium chloride due to their chemical similarities. Drinking water treatment processes use ozone to remove bromide from water, and this produces bromate as a byproduct. Bromide is soluble in water up to 35,000 mg/L at 20 C.
