Temperature affecting dissolved oxygen

xxcadiexx asks:

Hey I'm finding it hard to find an explanation (only statements,) for why warmer temperatures of water can hold less dissolved oxygen. This is needed for my coursework. Please help.

etutor answers:
If the heat given off in the dissolving process is greater than the heat required to break apart the solute, the net dissolving reaction is exothermic (energy given off). The addition of more heat (increases temperature) inhibits the dissolving reaction since excess heat is already being produced by the reaction. This situation is not very common where an increase in temperature produces a decrease in solubility.
