	ATSDR - ToxFAQs™: Sulfur Trioxide and Sulfuric Acid

	Sulfuric Acid - MSN Encarta
		In 1740 the acid was produced successfully on a commercial scale by burning sulfur and potassium nitrate in a ladle suspended in a large glass globe partially filled with water.
		When concentrated sulfuric acid is heated, it behaves also as an oxidizing agent, capable, for example, of dissolving such relatively unreactive metals as copper, mercury, and lead to produce metal sulfate, sulfur dioxide, and water.
		The trioxide is dissolved in concentrated sulfuric acid, and at the same time a regulated influx of water maintains the concentration at a selected level usually about 95 percent.

	Sulfuric acid - Wikipedia, the free encyclopedia
		Sulfuric acid is a constituent of acid rain, being formed by atmospheric oxidation of sulfur dioxide in the presence of water.
		Sulfuric acid is produced in the upper atmosphere of Venus by the sun's photochemical action on carbon dioxide, sulfur dioxide, and water vapor.
		The standard first aid treatment for acid spills on the skin is, as for other corrosive agents, irrigation with large quantities of water: in the case of sulfuric acid it is important that the acid should be removed before washing, as a further heat burn could result from the exothermic dilution of the acid.

	Sulfuric Acid Release Paper - Quest Consultants Inc.
		In the summer of 1991, an experimental program was conducted to determine the amount of equilibrium sulfuric acid that would pool, or fall to the ground, when the acid, both alone and as an emulsion with alkylation hydrocarbons, was released to the atmosphere.
		In 1990, a comparison of HF and sulfuric acid alkylation risks (4) estimated that a release of a sulfuric acid/alkylation hydrocarbon emulsion could result in 10 to 65 percent of the sulfuric acid becoming airborne.
		The volume fraction of acid and hydrocarbon composing each emulsion was determined by trapping a sample of the emulsion in a tubular sight glass, allowing the emulsion to separate, and reading the level of the acid/hydrocarbon interface.

	Sulfuric acid: Pumping up the volume
		In the late 15th century, Basilius Valentinus described two ways to prepare sulfuric acid; one was by burning sulfur with potassium nitrate, or saltpeter, and the second was by distilling the acid from a mixture of silica and ferric sulfate (vitriol—hence the name “oil of vitriol” used by alchemists).
		Until the 18th century, demand for sulfuric acid was slight; small amounts were consumed in preparing nitric and hydrochloric acids for use in treating or assaying nonferrous metals.
		In the latter part of the 19th century, the demand for sulfuric acid expanded further as ammonium sulfate (used as a fertilizer) began to be made from ammoniacal liquors formed as a byproduct of gas works.
