Under no circumstances must the gas be inhaled or smelled. It is not usually prepared in a school laboratory. If need be, the gas should be prepared in a fume chamber. Preparation of carbon monoxide 1.By dehydrating oxalic acid with hot concentrated sulphuric acid Carbon monoxide is prepared with the help of oxalic acid and concentrated sulphuric acid as shown below. Oxalic acid has the formula . Sulphuric acid reacts with oxalic acid and removes from it one molecule of water (both the hydrogen atoms, along with an oxygen atom). The product left behind due to this reaction, is a molecule of carbon dioxide and a molecule of carbon monoxide. The carbon dioxide can be removed by passing it through a concentrated solution of potassium hydroxide. … Read More »CARBON (II) OXIDE (CARBON MONOXIDE)
