1 PHYSICAL AND CHEMICAL PROPERTIES. Carbon monoxide is a highly poisonous, odorless, colorless, and tasteless gas. It is very flammable in air. over a wide range of concentrations (George 2001) and burns in air with a bright blue flame (OâNeil et al. 2006). It becomes a liquid at 81.62 K (-191.53 Â°C) and is insoluble in water above 70 Â°C (George 2001). The physical and chemical properties of carbon monoxide are shown in Table 4-2.
