What are the solubilities of gases in water?

1 Answer

Well all gases have some solubility in water........


You know that water is a remarkable solvent, and most substances have some greater or lesser water solubility. Oxygen is a small molecule, that can certainly can be solvated by water, to the tune of #10-20*mg*L^-1# at standard pressure. As a gas, oxygen is MORE soluble in COLD water, which is possibly the region why fisheries towards the north and south pole, i.e. colder waters, are prolific.
