A chemistry lab offers several different ways in which a person can test a gas to determine if it is carbon dioxide, or CO2: Light a splint. Collect carbon dioxide gas in a tube by downward delivery or using a gas syringe. Light a splint, which is a long, thin strip of wood. Insert the lit splint into the tube with the gas. If carbon dioxide is in the tube, the flame will go out. Place a piece of moist litmus paper into the tube with the carbon dioxide gas.
