Fractional distillation

Measure 55 mL of 40% ethanol
Place 50 mL of ethanol in your distilling flask taking care that no liquid enters the side arm.
Place the remaining 5 mL of ethanol in a test tube and set aside for procedure 2.
Add a few marble or porcelain chips to the distilling flask to prevent bumping. Bumping is a term given to irregular boiling
Assemble the rest of the apparatus for a simple distillation set-up. You may ask assistance from your instructor
Cover the top of the distilling flask with a cork fitted with a thermometer. Make sure that the tip of the thermometer bulb is just below the side arm of the distillation flask
