Colligative Properties
If colligative properties depend on the amount of the solute in the solvent then the equations defining them must include a concentration term and sure enough they do Over the next few pages you will be introduced to the equations in the context of the specific properties but for now simply note the similarities in structure for the equat |

Colligative Properties 5 1 Introduction Properties of solutions that depend on the number of molecules present and not on the kind of molecules are called colligative properties These properties include boiling point elevation freezing point depression and osmotic pressure |

Colligative properties CH102 General Chemistry Spring 2014
There are four colligative properties vapor-pressure lowering boiling-point elevation freezing-point depression osmotic pressure Each of these properties is due to the effect of solute on entropy changes and so spontaneity We will see that the cause of each of the properties is changes necessary to keep free energy in balance |
What are the ligative properties of a solvent?
Colligative properties include vapor pressure, boiling point, freezing point, and osmotic pressure. The addition of a nonvolatile solute (one without a measurable vapor pressure) decreases the vapor pressure of the solvent.
Why do colligative property experiments give a number average molecular weight?
Because colligative properties depend on the number of molecules, we expect, and will show, that colligative property experiments give a number average molecular weight. Figure 5.1 shows the vapor pressure of a liquid for pure liquid and for a solution with that liquid as the solvent.
Are vapor pressure and osmotic pressure colligative properties?
As we will see, the vapor pressure and osmotic pressure of solutions are also colligative properties. When we determine the number of particles in a solution, it is important to remember that not all solutions with the same molarity contain the same concentration of solute particles.
What is a colligative property of a solution?
There are a few solution properties, however, that depend only upon the total concentration of solute species, regardless of their identities. These colligative properties include vapor pressure lowering, boiling point elevation, freezing point depression, and osmotic pressure.
Concentration and Colligative Properties
If colligative properties depend on the amount of the solute in the solvent, then the equations defining them must include a concentration term, and sure enough, they do. Over the next few pages you will be introduced to the equations in the context of the specific properties, but for now, simply note the similarities in structure for the equat
ΔP = χP0
0% pure solvent Since we know that vapor pressure is a surface phenomenon, we see that one obvious reason for the reduction in vapor pressure is that there are fewer surface locations to put a molecule. So the solvent will have to have a reduction in vapor pressure because fewer molecules are present to leave the surface. The plot of mole f
Colligative Property 2—freezing point depression is explained
Freezing point depression is again thermodynamic effect. In order to make ice, which is a pure crystal, extra work must be done to separate the solute from the solvent—NaCl from water, for example. This means you need to reduce the freezing point to thermodynamically drive the reaction. This has the advantage of allowing for the deicing of st
