Sulfuric acid (American English) or sulphuric acid (historical spelling), also known as oil of vitriol, is a mineral acid composed of the elements sulfur, oxygen and hydrogen, with molecular formula H 2 SO 4.It is a colorless, odorless, and viscous liquid that is soluble in water and is synthesized in reactions that are highly exothermic.. Its corrosiveness can be mainly ascribed to its strong EWG's Guide to Healthy Cleaning SULFURIC ACID SubstanceEWG's Guide to Healthy Cleaning is a free, searchable online tool providing consumers with safety ratings for common household cleaners.

NIOSH METHOD 7908 FOR NON-VOLATILE ACIDS:SULFURIC AND PHOSPHORIC ACIDS NIOSH Method 7908 specifies the use of a 37-mm diameter quartz fiber filter or 0.45-m pore size polytetrafluoroethylene (PTFE) filter for the collection of H2SO4and/or H3PO4in workplace air. Nitric acid HNO3 - PubChemNitric acid is a nitrogen oxoacid of formula HNO3 in which the nitrogen atom is bonded to a hydroxy group and by equivalent bonds to the remaining two oxygen atoms. It has a role as a protic solvent and a reagent. It is a conjugate acid of a nitrate. Nitric acid (HNO3).
"A standard is recommended for exposure to sulfuric-acid (7664939) at the workplace, which is designed to protect the health and safety of workers over a working lifetime. The biological effects of exposure to sulfuric-acid are described, and information is given on environmental sampling and analytical methods." Sulfur Trioxide & Sulfuric Acid Public Health Statement Sulfur trioxide is generally a colorless liquid but can also exist as ice- or fiber-like crystals or as a gas. When sulfur trioxide is exposed to air, it rapidly takes up water and gives off white fumes. It combines with water, releasing considerable heat while forming sulfuric acid. It also reacts violently with some metal oxides. Sulfur trioxide is also called sulfuric oxide and sulfuric
sulfuric acid are more likely to be found in air than sulfur trioxide. If you are interested in learning more about sulfur dioxide, the Agency for Toxic Substances and Disease Registry has developed a separate profile about it. Sulfuric acid is a clear, colorless, oily liquid that is very corrosive.

Breakthrough times of sulfuric acid through neoprene or polyvinyl chloride are greater than one hour reported by (normally) two or more testers. ACGIH There is some data suggesting that the breakthrough times of sulfuric acid (< 30%, 30-70%, and >70%) through polyethylene, Saranex, chlorinated polyethylene, neoprene, nitrile, polyvinyl chloride Sulfuric acid - Reactivities / IncompatibilitiesWater and sulfuric acid:Dilution of sulfuric acid with water is vigorously exothermic, and must be effected by adding acid to water to avoid local boiling. Mixtures of sulfuric acid and excess snow form powerful freezing mixtures. Fuming sulfuric acid (containing sulfur trioxides) reacts violently with water.
