SOLUTIONS ( PART 2)



 Solubility = It is the maximum amount of solute that can be dissolved in specified amount of solvent at certain temperature.

It depends upon : Nature of solute and solvent
       
                           Temperature and pressure



Dissolution= It is the amount of solid solute that dissolves in a solvent and the concentration solid solute increases in the solution.


Crystallization= The solute particles in the solution collides with solid solute and separates out of solution .



                    Saturated Solution                                        Unsaturated Solution
   
             Solution in which no more solute                         Solution in which more solute can be dissolved
             can be dissolved at the same                               at the same temperature and pressure.
             temperature and pressure.



             FACTORS EFFECTING SOLUBILITY ( Solubility of a solid in a liquid)

             Temperature =    solubility is directly proportional to the temperature

             If the dissolution process is endothermic = Solubility increases
             If the dissolution process in exothermic =   solubility decreases


           Pressure = No effect on solubility ( as solid and liquids are highly in-compressible) 

           Solubility of gas in liquid                         

           The solubility of gases in liquid increases increases with the increases in pressure
