Sulfur oxoacids

The sulfur oxoacids are chemical compounds that contain sulfur, oxygen and hydrogen. The best known and most important industrially, is sulfuric acid. Sulfur has a number of oxo acids however some of these are only known from their salts (these are shown in italics in the table below. The acids that have been characterised contain a variety of structural features for example
 * tetrahedral sulfur when coordinated to oxygen
 * terminal and bridging oxygen atoms
 * terminal and bridging peroxo groups
 * terminal S=S
 * chains of (-Sn-)
