Question:
Despite consulting a variety of sources, I do not yet have a satisfactory explanation as to why carbon dioxide is more soluble in cold water than it is in warm water.


Replies:
David,

Any water soluble gas becomes more soluble as temperature decreases because, in and of themselves, gas molecules have little affinity for each other -- after all, that is why they are gases. When dissolved in water, CO2 forms weak bonds with the water molecules. The lower the temperature, the stronger the bonds, the greater the amount of CO2 that can be dissolved.

Regards,
ProfHoff 301
