Hydrogen bromide (HBr) is a very corrosive, toxic gas. This gas can be fatal if it is inhaled. It is corrosive to the respiratory system, eyes, and through skin contact. When it is in liquid form or in a mist it will cause burns to all body tissue it falls upon.
Properties
Hydrogen Bromide is an extremely irritating, nonflammable, corrosive gas with a pungent odor at room temperature. It will fume in moist air because of the formation of hydrobromic acid; it is the diatomic molecule HBr. Under normal conditions hydrogen bromide is a gas but it can be turned into liquid. Hydrobromic acid is then formed after hydrogen bromide is dissolved in water. Hydrobromic acid and Hydrogen bromide are not the same but they are related.
Occurrences
Hydrogen Bromide does not occur naturally it is made by humans in a lab. It is very toxic and corrosive so you must handle it carefully in the lab or when you are using it.
Uses
Hydrogen bromide is a reagent and a catalyst in many organic reactions. It is also used in many inorganic bromides as well as in cracking of petroleum products. Other than this there are not many uses of hydrogen bromide. Sense it is so toxic you have to handle it with piping material with proper corrosive protection on it. When transporting the gas keep out of the sun and away form heat.
Toxic
Hydrogen bromide is very toxic. It can kill you if you inhale it or if you touch it or it gets on your eyes it can kill you. If you get some on you, you should wash it all off immediately because it will start to corrode your skin. If you inhale hydrogen bromide it will start to corrode your respiratory system. When hydrogen bromide is in liquid form it will cause burns over all of the skin that it touches.
