      Sulfuric acid (H2SO4) is a basic raw material used in a wide range of industrial processes and manufacturing operations. Almost 70 percent of sulfuric acid is used in the production of phosphate fertilizers. Other uses include copper leaching, inorganic pigment production, petroleum refining, paper production, and industrial organic chemical ...

      As expected, the addition of sulfuric acid reached the target pH with the least amount of material. When sulfuric acid was added to the irrigation water collected from the golf course in Fountain Hills, which was the most highly buffered of the three water sources, the equiva-lent of about $50 per acre-foot was needed to lower the pH to 6.5.

      Sulfuric acid is produced by thermally decomposing sulfur and/or spent sulfuric acid to produce sulfur dioxide gas. The sulfur dioxide (SO2) is then converted to sulfur trioxide (SO3) by reaction with oxygen (O2) in the presence of a catalyst.Finally, the sulfur trioxide (SO3) is reacted with water (H2O) to produce sulfuric acid.

      Hydrogen sulfide has a variety of industrial uses. Its major use is in the production of elemental sulfur and sulfuric acid. Sulfur recovered from the treatment of sour gas in 1986 accounted for 14 million tons, or 25% of total world sulfur production. In 1995, the production of sulfuric acid was estimated to consume 1.1x10
