Structure Of Iodous acid
The chemical formula of iodous acid is HIO2. It is made up of a hydrogen atom, an iodine atom, and two oxygen atoms. An iodine atom is bonded to an oxygen atom and a hydroxyl group. The two structural isomers of HIO2 are HOOI and HOIO, where H, O, and I atoms are arranged differently within the molecules.
Iodous Acid Formula
Iodous acid is an iodine oxoacid and is also known as hydroiodic acid. Its chemical formula is HIO2, and it is the conjugate acid of an iodite. It is extremely unstable and can only be present briefly in aqueous solutions. Its molecular formula is 159.911 g/mol, while its monoisotopic mass is 159.90213 g/mol. An iodite ion, or iodine dioxide anion, is called halite. The oxidation number of iodine in iodous acid is +3. The salts of iodous acid are known as iodites and are observed, but they are very unstable and are never isolated. These salts are disproportionate and quickly form molecular iodates and iodine. The hydrogen bond donor count in iodous acid is 1, while its hydrogen bond acceptor count is 2.
