Experiment 11 - A Simple Covalent Compound: Synthesis and Properties Jonathan Brate February 2nd, 2009 Dr. Padolik Purpose: One purpose for performing Experiment 11 was to synthesize tin and iodine, and observe what happens during the process, as well as to see how high of a percent yield could be obtained. Another purpose was to observe the behavior of multiple binary bonds, both covalent and ionic, when mixed with a solvent and heated. Using the electronegativities to determine whether a bond was ionic or covalent was a topic covered in lecture that was applied towards Experiment 11. Also, the difference in physical properties between covalent and ionic bonds was a topic covered in lecture that was observed in the experiment. One laboratory technique that was employed during the experiment was the use of pressurized error to speed up the evaporation process of the dichloromethane, in order to obtain the tin tetraiodide. Another laboratory technique was the use of a burner in order to observe the behaviors of the binary compounds when heated. Experimental Procedure: The procedure followed was that given in the lab manual: Sprague, Alexander, Padolik & Steffel, Laboratory Experiments for First Year Chemistry, 3rd ed. pp. 11- 1 to 11-5, except it was performed individually and laboratory balances were used instead of analytical balances. Method 2 was used to evaporate the CH 2 Cl 2 .
