DESCRIPTION

Sulfuric Acid occurs as a clear, colorless or slightly brown, oily liquid. It is very caustic and corrosive. It is miscible with water and with alcohol with the generation of much heat and contraction in volume. Sulfuric Acid should be added cautiously to the diluent when mixed with other liquids. Some commercially available concentrations of Sulfuric Acid are expressed in degrees Baumé (°Bé) and others (above 93.0%) as a percentage of H₂SO₄. The more common concentrations are 60 °Bé and 66 °Bé, equivalent to 77.67% and 93.19% of H₂SO₄, respectively, and 98.0% of H₂SO₄. Its specific gravity varies with the concentration of H₂SO₄ (see Sulfuric Acid Table, Appendix IIC).
