Carbon Monoxide

• De Lassone - In 1776, prepared carbon monoxide by heating zinc oxide and wood charcoal

  Cruik Shank in 1800, found carbon monoxide to be a compound of carbon ad oxygen
• Octane - C8H18

  Found in petrol
• Formic acid - HCOOH
• In the laboratory preparation of carbon monoxide, conc. H2SO4 acts as a dehydrating agent and removes a molecule of water from the formic acid
• Carbon monoxide is passed through the caustic potash solution which absorbs any carbon dioxide formed
• Carbon Monoxide is collected by the downward displacement of water as it is almost insoluble in water and as heavy as air
• Vapor density of carbon monoxide is 14
• Carbon Monoxide is very slightly soluble in water
• Carbon monoxide liquifies to a colorless liquid with high pressure and low temperature
• Carbon monoxide is highly toxic due to its ability to bind to haemoglobin more strongly than oxygen
• The boiling point of carbon monoxide is -192°C
• During normal respiration oxygen combines with haemoglobin to produce oxy-haemoglobin
• When carbon monoxide is inhaled a stable compound - carboxyl haemoglobin is formed
• A condition in which lack of oxygen which results in death is called asphyxia
• Fumes of burning tobacco contain traces of carbon monoxide
• Carbogen is a mixture of 95% oxygen and 5% carbon dioxide which is used in artificial respiration given to a victim of carbon monoxide poisoning
• Workers in factories should be made to wear a mask of hopcalite which is made up of MnO2 (50%), CuO (30%), CoO (13%), and Ag2O(7%) which converts carbon monoxide to carbon dioxide even at ordinary temperatures
• Carbon Monoxide burns in air with a pale blue flame but it is a non supporter of combustion
• Does not undergo thermal decomposition at any temperature
• Neutral to litmus
• Carbon reacts with heated metals forming carbonyls
• Reduces heated metallic oxides to metals
• Used in the metallurgy of iron'
• Used in preparation of methyl alcohol - CH3OH
