Introduction The physical properties of solutions that depend on the number of dissolved solute particles and not their specific type are known as colligative properties. These include freezing point depression, osmotic pressure, and boiling point elevation. In this lab, freezing point depression and boiling point elevation will be investigated. Purpose : What is the point of completing this lab Materials/Apparatus : List what you see on the virtual lab bench. Procedure : 1. Go to: http://www.chem.iastate.edu/group/Greenbowe/sections/projectfolder/animationsindex.htm 2. Scroll to the bottom of the page to the section Solutions – click on the Freezing-Point Depression experiment 3. Molar Mass Determination by Freezing Point Depression Experiment #1 , choose the following options: cold bath (click on the switch), and 100g of distilled H 2 O, click start. Record your data in the table.
