Dear ishrat,


CST:Critical Solution Temperature


Liquids and solids exhibit practically no change of solubility with changes in pressure. Gases as might be expected, increase in solubility with an increase in pressure. Henry's Law states that: The solubility of a gas in a liquid is directly proportional to the pressure of that gas above the surface of the solution.


If the pressure is increased, the gas molecules are "forced" into the
solution since this will best relieve the pressure that has been applied.
The number of gas molecules is decreased. The number of gas molecules
dissolved in solution has increased as shown in the graphic on the left.


Carbonated beverages provide the best example of this phenomena. All carbonated beverages are bottled under pressure to increase the carbon dioxide dissolved in solution. When the bottle is opened, the pressure above the solution decreases. As a result, the solution effervesces and some of the carbon dioxide bubbles off.


Two partially miscible liquids may become completely miscible at a higher
temperature since solubility increases with temperature generally. This miscibility temperature is
different for different compositions of the mixture. The highest miscibility temperature is called
the critical solution temperature or CST. Above this temperature, all compositions of this
mixture are completely miscible.










We are all IITians and here to help you in your IIT JEE preparation.

All the best.
