Procedure 1. Weigh the mixture 2. Record in data table 3. Get an Erlenmeyer flask and a funnel 4. Weigh the flask and record the measurement in the table 5. Put the funnel on the flask so the bottom of the funnel is in the flask 6. Fold the filter paper in half twice and pull out one flap to create a pocket to catch retentate when filtering the mixture 7. Level the balance to the weight of the paper by putting the paper on the balance and then zeroing it 8. Put filter paper in funnel with the pocket open 9. Pour mixture through the funnel slowly to avoid spills 10. Take out paper with the retentate and weigh the sand 11. Move the Erlenmeyer flask to a hot plate and put a two holed stopper in the flask 12. In one of the holes, put a thermometer into the hole and down into the mixture 13. Into the other hole, stick the glass tubing into it 14. Attach rubber tubing on the other end of the rod 15. Attach the other glass tube into the other end of the rubber tubing 16. Put the the end of the tubing into a test tube sitting in a beaker full of ice

Wait until the mixture inside the flask boils and let it boil until the mixture no longer boils 20. Then turn off hot plate and remove glass tubing from the test tube 21. Put the test tube in the test tube holder and take apart all the tubing and remove the stopper and take out the thermometer and glass tubing 22. Remove the Erlenmeyer flask and weigh it and record the data 23. Pour out the water and dry the flask completely 24. Then pour the test tube into the flask and weigh it 25. Record the measurement in the data table and then find differences of the flask measurements 26. Calculate the percentage of the mixtures components 27. Give flask to be tested for the purity of the alcohol...

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
