Carbonation refers to reactions of carbon dioxide to give carbonates, bicarbonates, and carbonic acid. In chemistry, the term is sometimes used in place of carboxylation, which refers to the formation of carboxylic acids.
- MOH + CO2 → M(HCO3)
- M'O + CO2 → M'CO3
Henry's law states that PCO2=KBxCO2 where PCO2 is the partial pressure of CO2 gas above the solution. KB is Henry's law constant. KB increases as temperature increases. xCO2 is the mole fraction of CO2 gas in the solution. According to Henry's law carbonation increases in a solution as temperature decreases.
