sulfuric acid (H2SO4)

a clear, colorless, oily, highly corrosive liquid that generates great heat when mixed with water. An extremely toxic substance, sulfuric acid causes severe skin burns, blindness on contact with the eyes, serious lung damage if the vapors are inhaled, and death if it is ingested. In industry, sulfuric acid is used in the manufacture of fertilizers, dyes, glue, and other acids; in the purifying of petroleum; and in the pickling of metals. Weak solutions of sulfuric acid are used in the treatment of gastric hypoacidity and serous diarrhea. Formerly called oil of vitriol.
