Introduction
1.Direct oxidation of C in limited supply of oxygen or air yields carbon monoxide.
2.On small scale pure CO is prepared by the passage of steam over hot coke.
3.The mixture of CO and Hydrogen gas thus produced is known as water gas or synthesis gas.
4.When air is used instead of steam, a mixture of CO and Nitrogen gas is produced, which is called producer gas. 5.Water gas and producer gas are very important industrial fuels. 6.Carbon monoxide in water gas or producer gas can undergo further combustion forming carbon dioxide with the liberation of heat. 7.Carbon monoxide is a colorless, odorless and almost water insoluble gas. 8.It is a powerful reducing agent and reduces almost all metal oxides, except alkali and alkaline earth metals, aluminum and a few transition metals. 9.This property of CO is used in the extraction of many metals from their oxide ores. 10.The highly poisonous nature of CO arises because of its ability to form a complex with hemoglobin, which is about 300 times more stable than the oxygen-hemoglobin complex. 11.This prevents hemoglobin in the red blood corpuscles from carrying oxygen round the body and ultimately resulting in death.
