Background: This was a three part lab to test the effectiveness of common techniques such as extractions and washing using various solutes and solvents. Part A tested the effectiveness of the extraction of dodecane using just water or water and tert-butyl methyl ether. For the first half of part A, the solution was dried with anhydrous magnesium sulfate and then decanted, while the second half of part A entailed drying with magnesium sulfate and then using a steam bath to evaporate the ether (ether evaporation was complete when the liquid no longer boiled at a temperature below dodecane’s boiling temperature). Part B tested the efficacy of extracting crystal violet from water with one dose of 10 ml of methylene chloride. Finally, part C tested the effectiveness of washing fluorene, using water in order to extract the crystal violet contamination. Results:
