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 |

Solutions 6 6 Colligative Properties of Solutions Colligative Properties of Solutions Liquids solutions experience the following four colligative properties: Vapor Pressure Reduction Boiling Point Elevation Freezing Point Depression and Osmotic Pressure over that of the pure solvent Top View Vapor Pressure Reduction Side View Pure Solvent |
Which unit is appropriate for calculating colligative properties?
More appropriate for calculations involving many colligative properties are mole-based concentration units whose values are not dependent on temperature. Two such units are mole fraction (introduced in the previous chapter on gases) and molality.
What determines the magnitude of a colligative property change?
Let’s look at how much the colligative property change was for the same solute/solvent combination—note that what determines the magnitude of the overall change is the amplification by the constant term—in other words, the bigger the constant, the bigger the change, and the clear winner is the RT term for osmotic pressure.
