Experimental Procedure HAZARD: Sulfuric acid, acetic anhydride and glacial acetic acid are corrosive to the skin. They are also irritants, and all operations in which these substances are used should be carried out under the hood. Prepare a hot-water bath by heating a 400-ml beaker containing about 200 mL of water. 1. Use a centigram balance and...
