Characteristics and uses of Sulfur

Post  gill on Tue Dec 28, 2010 1:03 am

Sulfur is a soft, pale yellow, odorless, brittle solid. It is insoluble in water, but soluble in carbon disulfide. It burns with a blue flame, oxidizing to sulfur dioxide. Sulfur exists in several crystalline and amorphous allotropes. The most common form is yellow, orthorhombic alpha-sulfur, which contains puckered rings of S8. Sulfur is multivalent and combines, with valence 2, 4, or 6, with almost all other elements. The best known sulfur compound is hydrogen sulfide (H2S). This is a toxic gas that smells like rotten eggs; the smell is used in stink bombs, many of which release a small amount of hydrogen sulfide.
Sulfur's main commercial use is as a reactant in the production of sulfuric acid (H2SO4). Sulfuric acid is the industrialized world's number one bulk chemical, required in large quantities in lead-acid batteries for automotive use.
Sulfur is also used in the vulcanization of natural rubber, as a fungicide, in black gunpowder, in detergents and in the manufacture of phosphate fertilizers. Sulfur is a vital element for all forms of life. It is a component of two amino acids, cysteine and methionine.

Sulfur(sulphur) can be considered the most important mineral (element) we have. The main reason for this is in it's use in the production of sulfuric acid.Sulfuric acid is the most important chemical produced in the world.More sulfuric acid(H2SO4) is produced than any other chemical.It is the starting point for almost all other chemicals. It has been said that a nations industrial output can be based on their consumptiom of sulfuric acid.One last "factoid" the antidote,if administired quickly enough for cyanide poisoning is colloidal sulfur injected directly into the blood stream.
