Compounds of sulphur

Sulfur forms compounds in oxidation states -2 (sulfide, S2-), +4 (sulfite, SO32-), and +6 (sulfate, SO42-). It combines with nearly all elements. An unusual feature of some sulfur compounds results from the fact that sulfur is second only to carbon in exhibiting catenation--i.e., the bonding of an atom to another identical atom. This allows sulfur atoms to form ring systems and chain structures. The more significant sulfur compounds and compound groups are as follows.

One of the most familiar sulfur compounds is hydrogen sulfide, also known as sulphureted hydrogen, or stinkdamp, H₂S, the colourless, extremely poisonous gas responsible for the characteristic odor of rotten eggs. It is produced naturally.... View More
