L'effet de la loi de Henry sur la dissolution du CO2 dans les eaux naturelles

The solution coefficient of CO2 in water increases three times when temperature decreases from 35 to 0°C. It was deduced from this, by some researchers, that cold waters are richer in CO2 than warm waters, and thus more aggressive towards limestone. Indeed, CO2 content of water is, according to Henry's law, the product of the solution coefficient by the partial pressure of CO2 in air. This partial pressure varies much more than solution coefficient, and often in the opposite direction.
