Carbon monoxide

Carbon monoxide (CO) is an inorganic compound in the air. Under normal conditions, carbon monoxide is a colorless, odorless, odorless, hardly water-soluble gas with a melting point of -199 ° C and a boiling point of -191.5 ° C. Under standard conditions, the gas density is 1.25g / L, which is very different from air density (1.293g / L under standard conditions, which is also one of the factors prone to gas poisoning. It is a neutral gas.
