Unformatted text preview: Colligative Properties: Freezing Point Depression and Molar Mass Colligative Properties Freezing point depression Boiling point elevation Colligative Property Law T=K*m Determine solute molar mass based on freezing point depression Homogeneous mixtures with two or more substances Solvent Major solution component Solute Minor solution component Physical properties of a solution resemble those of the solvent Colligative properties are influenced by the solute concentration Freezing point depression Antifreeze (solute) to lower the freezing point of water (solvent) in a car radiator Boiling point elevation Salt (solute) to increase boiling temperature of water (solvent) when cooking pasta T=Km T is the freezing point lowering or boiling point elevation (C) K is the constant specific for each solvent (C/m) K fp- molal freezing point depression constant K bp- molal boiling point elevation constant m is the molality of solution (moles of solute per kilogram of solvent)...
