| Physical Description | Shipped in solution with sulfuric acid (solutions are usually 40% nitrosylsulfuric acid and 54% sulfuric acid (Hawley)). Solution is a straw-colored oily liquid with a sharp odor. When pure, a crystalline solid decomposing at 73 °C. Very irritating to skin and eyes. Used to make dyes and other chemicals.[Merck Index] Sulfuric acid solution: Straw-colored liquid with a sharp odor[CAMEO] Light yellow crystals[Sigma-Aldrich MSDS] |
