Similar term(s): bromate ion, bromate compound.
BrO3-. An inorganic anion, bromate is tasteless and colourless,
with a low volatility. As a moderately strong oxidant, bromate is reactive.
Normally, bromate is not found in nature, but it is a water disinfection
byproduct. It is formed during ozonation when ozone used to disinfect drinking
water reacts with (oxidises) naturally occurring bromide ions. Bromate is the
main cause for concern of ozonation as water treatment method. The amount of
bromate produced is influenced by the amount of (naturally occurring) bromide in
