Sulfur (16)
- Sulfur compounds include the sulfide minerals, such as:
- Pyrite (Iron Sulfide) – FeS2
- Cinnabar (Mercury Sulfide)
- Galena (Lead Sulfide) – PbS
- Sphalerite (Zinc Sulfide)
- Stibnite (Antimony Sulfide)
- Sulfates Minerals, such as:
- Gypsum (Calcium Sulfate) – CaSO4.2H2O
- Alunite (Potassium Aluminium Sulfate)
- Barite (Barium Sulfate)
- Element’s largest use is to produce sulfate and phosphate fertilizers. Sulfuric Acid is also a primary industrial chemical.
- Other known uses for the element are in matches, insecticides and festicides, and other Biochemical processes.
- The Principal ores of copper, zinc, nickel, cobalt, molybdenum, and other metals are sulfides.
- Sulfuric Acid and SO3 = Oleum, a solution of Pyrosulfuric Acid (H2S2O7) in Sulfuric Acid.
- Sulfurous Acid – H2SO3
- Sodium Dithionite – Na2S2O4
- Sulfur reacts directly with methane to give Carbon Disulfide, used to manufacture cellophane and rayon.
- Most important form of sulfur for fertilizer is the mineral Calcium Sulfate.
- Sulfur is part of many bacterial defense molecules – most of Beta-lactam anti-biotics.
- Elemental Sulfur is a common fungi for grapes and many vegetables.
