by the dehydration of oxalic acid crystals. The dehydrating agent used is concentrated sulphuric acid. When a mixture of oxalic acid crystals and concentrated sulphuric acid is heated in a flask, the acid not only removes the water of crystallisation from the hydrated acid, but alsgE removes the elements of water from the anhydrous acid remaining. The resulting product is a mixture, of carbon monoxide and carbon dioxide.
