(iii) oxidation state of oxygen changes in the reaction at anode. For example, when carbon monoxide is passed over hot iron oxides, the oxides are reduced to metallic iron, while the carbon monoxide is oxidized to carbon dioxide. The CO combines with hemoglobin, giving the bright pink color that consumers associate with freshness. The carbonyl vapour when subjected to still higher temperature undergoes thermal decomposition giving pure metal. Thus, carbon monoxide may have a physiological role in the body, such as a neurotransmitter or a blood vessel relaxant. Budavari, Susan, ed. . . The color persists even upon thawing and holding near room temperature thus preserving the fresh look of the product. v] Displaces hydrogen from cold water forming a colourless solution.
