Beginning Question: Safety: There are flammable reagents, there should be no open flames in the lab during this experiment. There are toxic reagents, be sure to perform all work in the fume hood so harmful vapors are drawn out of the room. There are also corrosive reagents, be sure to wear goggles and gloves and work carefully to avoid spilling the reagents. Procedure: Part one: Part two: 1. Obtain 20mL of 10% NaOH in a 59-mL beaker. 2. Heat the NaOH solution to boiling, then add 1.8g of sulfur, stir constantly and make observations. Stir the solution until all sulfur dissolves. 3. Divide sulfur solution equally in two identical beakers and allow to cool to 70 degrees C 4. Add 0.5mL of Aliquat 336 catalyst to one of the beakers followed by 2.0mL of 1,2- dichloroethane to both 5. Stir both mixtures with glass stir rod and make observations. Stir until all reactions are complete. Pour remaining aqueous phase into the waste container 6. Discard the 1,2-dichloroethane and the NaOH aqueous phase in the waste container 7. Wash the white-yellowish material with water very thoroughly
