# What are the solubilities of gases 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 $10 - 20 \cdot m g \cdot {L}^{-} 1$ 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.
