Perbromic acid is the

oxidizing, though dilute perbromic acid solutions are slow oxidizing agents. It is the most unstable of the halogen(VII) oxoacids. It decomposes rapidly on standing to bromic acid and oxygen, which releases toxic brown bromine vapors. It can be used in the synthesis of perbromate salts, by reacting with a base

.

Perbromic acid is unstable and cannot be formed by displacement of chlorine from perchloric acid, as periodic acid is prepared; it can only be made by protonation of the perbromate ion. Perbromic acid is stable in aqueous solutions no greater than 6M. Perbromic acid solutions greater than 6M are unstable in air, where an autocatalytic decomposition of the compound will occur. Metals such as Ce⁴⁺ and Ag⁺ can also catalyze the compound.

Discovery

Perbromic acid was discovered through the decay of a radioactive selenate sample, SeO₄⁻², where bromine crystals were exposed to gamma radiation.

Safety

Perbromic acid is corrosive and an irritant, therefore it is extremely dangerous to the skin, eyes, airways, and digestive tract. Overexposure can lead to various effects such as suffocation of the lungs, loss of consciousness, and death. Due to its toxicity, prolonged or repeated exposure could also lead to organ damage via the lungs, kidneys, and intestines.
