Department of Chemistry [Colligative Properties & Osmotic Pressure] Purpose : The experiment this week had two different purposes. The first is to teach us about freezing points. This lab was designed to show us the freezing point of a pure solvent‚ in comparison to a solvent in a solution with a non-volatile solute. The second goal of the experiment is to teach students about osmosis. In the experiment‚ we got to observe osmosis as well as understand dialysis

Properties of Chemical Reactions Ms. Whitty‚ Science 10 Fiona Adams‚ November 1st‚ 2012 Introduction Chemical reactions are a part of our daily lives‚ from rusting metal to making bread to leaves changing colour in the fall. A chemical reaction is the process that occurs when two or more substances combine to produce a chemical change. When a chemical reaction takes place‚ the change is indicated by one or more qualitative properties. The colour or odor could change‚ gas could be produced
