Examples
Researchers discovered that the invasive Hydrilla builds up extreme concentrations of bromine compounds, 20 times greater than the concentrations in the lake bottom mud and 500 to 1,000 times greater than in lake water.
Nicknamed AETX, the toxin has an unusual chemical structure requiring building blocks rich in the element bromine, says Susan Wilde, an aquatic ecologist at the University of Georgia in Athens.
Bromine water I believe may be added, but that I have not used hitherto, and therefore cannot answer for its effects.
Bromine water is a convenient agent for oxidizing cobaltous to cobaltic ions (see Chapter XV).
Treat the distillate with a few drops of bromine water and boil for a short time.
"Bromine Water" is simply bromine shaken up with water till no more is dissolved.
It is used as an indicator in volumetric silver assaying, and for the separation of iodine from bromine.
