Unformatted text preview: Michael Chelala TA: Jaylene Ollivierre Date of Experiment: 9/10/2007 Submission Date: 9/17/2007 Crystallization and Melting Point Objective: Remove the decolorizing carbon from the unknown by filtration, and then crystallize the unknown in order to determine the melting point. Use the melting point to determine the identity of the unknown. Reaction Equations: None Procedure: Heat 18mL of water in a 50mL Erlenmyer Flask with a hot plate. Get a 50mL beaker and dissolve .248 grams of unknown #500 in 15mL of water. Use a gravity funnel, some filter paper, and a 20mL beaker to filter the decolorizing carbon from unknown #500 solution. Wash the filter paper with 1mL of water to make sure left over crystals go through. Cool off the 20mL beaker in an ice bath for 8 minutes and until the solution crystallizes. Connect the rubber tube to the filter an ice bath for 8 minutes and until the solution crystallizes....
