When the temperature of a river, lake, or stream is raised abnormally high, usually due to the discharge of hot water from some industrial process, the solubility of oxygen in the water is decreased. Carbon monoxide ( chemical formula CO) is a colorless, odorless, tasteless, flammable gas that is slightly less dense than air. It is produced by the incomplete combustion of carbonaceous fuels such as wood, petrol, coal, natural gas and kerosene. This is because carbon monoxide has a low solubility in the alveolar-capillary membrane but a high solubility in blood. The solubility of H 2 in methanol and methyl formate is lower than that of CO in methanol and methyl formate.
