- Definition of HBrO4
HBrO4, also known as perbromic acid, is a strong acid and strong oxidizing agent with the chemical formula HBrO4. This acid has a molar mass of 128.91 g/mol, consisting of 1 hydrogen atom (H), 1 bromine atom (Br), and 4 oxygen atoms (O). The molecular structure of perbromic acid shows the bond between bromine and oxygen atoms, creating a system of simultaneous bonding with the hydrogen atom. In water solution, HBrO4 will dissociate into H+ and BrO4- ions.
