Concentrated Sulfuric Acid

Other Names: Hydrogen sulfate, oil of vitriol, battery acid, 660 Baume sulfuric acid (93.2%), 98% sulfuric acid
Formula: H
2SO4
Sp. Gr.: 1.84
Viscosity: Less than 160 cPs.

Remarks: Sulfuric acid is one of the most important of the heavy chemicals. It is strongly corrosive, dense, oily, colorless to dark brown depending on purity. It is miscible with water in all proportions, but great caution is necessary in mixing due to evolution of much heat that may cause explosive spattering. It is very reactive, dissolves most metals; concentrated acid oxidizes, dehydrates, or sulfonates most organic compounds, often causing charring. Used in making fertilizers, as a source of many chemicals, in petroleum refining, in making paints and pigments, in production of iron and steel, in the manufacture of rayon and cellulose film, in making industrial explosives. Some of the high concentrations are prone to "salt out," which can cause the pump to bind up in the bushing areas. Applicants for handling sludge or spent sulfuric acid should be reviewed with user.

Pump Notes: Because of the corrosive characteristics of this liquid consult the pump manufacturer for specific recommendations.
