Today you will use GC to explore the behavior of a simple chemical system, and to answer some focus questions about the system. The system consists of two liquid solvents , water and 1,1,2,2-tetrachloroethane, and a third liquid, the solute , that dissolves to some extent in both solvents. You will put the two solvents in contact, add the solute, and explore the manner in which the solute distributes itself between the two solvents. Your goal will be to develop answers to the following focus questions below. Give a molecular-level description of the process by which a solute distributes between 2 solvents, and of the equilibrium situation.
Most organic liquids are toxic and flammable.
Avoid contact with skin, and keep away from open flames or sources of heat. Experimental Record all data in your notebook. Obtain the necessary equipment and clean the glassware thoroughly using brushes and Alconox detergent. Rinse with distilled water and dry thoroughly. Two solutes will be investigated initially by your section.
