Effect of Temperature on Solubility

What happens to the solubility of a salt or a gas at constant pressure when the temperature of the solution changes?
This can be treated as just a special case of Le Chatelier's Principle .....

And AUS-e-TUTe has just added new resources to help you understand the effect of temperature on solubility.
AUS-e-TUTE Members should log-in to use the new tutorial (includes a drill), game, test and exam.

If you are not an AUS-e-TUTE member, there is non-interactive "free-to-view" tutorial currently available for evaluation purposes at http://www.ausetute.com.au/solubilitylcp.html

Solutes, Solvents and Solutions

Seems like the science of solutions is simply seething with "s" sounds:
  • solute
  • solvent
  • solution
  • solubility
  • solvation
  • saturated (and unsaturated)
 but what do they mean?

AUS-e-TUTE has just added new resources to help you find out, and, understand the differences!
AUS-e-TUTE Members should log-in to use these new "Solutions Concepts" resources.
