Boiling Point Elevation and Freezing Point Depression From UCDavis Chemwiki Two examples of colligative properties are boiling point and freezing point: due to the addition of solutes, the boiling point tends to increase and freezing point tends to decrease. 

Colligative Properties and Dissociation of Electrolytes From UCDavis Chemwiki Thus far we have assumed that we could simply multiply the molar concentration of a solute by the number of ions per formula unit to obtain the actual concentration of dissolved particles in an electrolyte solution. 

 Colloids From ChemPRIME Solutions are homogeneous. 

Dissolution of Gases in Liquids From UCDavis Chemwiki Gases dissolve in liquids, but usually only to a small extent. 

Dissolution of Liquids in Liquids From UCDavis Chemwiki Whereas all gases will mix to form solutions regardless of the proportions, liquids are much more fussy. 

  Dissolution of Solids in Liquids From ChemPRIME Entropy of dissolution As anyone who has shuffled a deck of cards knows, disordered arrangements of objects are statistically more favored simply because there are more ways in which they can be realized. 

Effects of Temperature and Pressure on Solubility From UCDavis Chemwiki Experimentally it is found that the solubility of most compounds depends strongly on temperature, a gas, and on pressure as well.

 Fractional Distillation From ChemPRIME When a pure substance is mixed with another pure substance in which it is soluble, the substances become completely interspersed at the molecular level.
