- the eugenol and water distillate you collect is apt to be cloudy, particularly the first part of this distillate. Explain why.CREATE A SCHEMATIC DIAGRAM FOR THIS PROCEDURE: C. Preparation and storage of standard solutions 1. Use the weighed and transferred NaCl powder in procedure B. Dissolve it in about 10 mL distilled water. Use a stirring rod to gently stir the solution until it has been dissolved to an extent. Make sure you will not incur any noise while stirring. 2. When the NaCl powder is partially dissolved, transfer the resulting solution into a 100 mL volumetric flask. Use a stirring rod and funnel. 3. Repeat steps 1 and 2 until no NaCl remains in the beaker and until you are almost at the mark of the volumetric flask. 4. Rinse the last portion of the solution from the stirring rod into the volumetric flask with a stream of water from the wash bottle. Rinse the funnel and remove it. Dilute the solution in the flask using a Pasteur pipette until the bottom of the meniscus is even with the graduation mark. 5. Put a stopper on the volumetric flask.

After some analysis, you determine that the mixture contains toluene, hexane,benzoic acid, water, sodium chloride, and sand. Explain how you would isolate pure hexane from thismixture. Remember that you can use techniques such as filtration, extractions, and acid/base chemistrythat we learned earlier in this course in addition to distillation. You may need to look up solubilities and/orboiling points online to solve this problem. You only need to isolate the hexane?
