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 Check all connections for tightness Heat the contents of the flask to boiling. Adjust the flame when the sample is already boiling. Make sure that it does not boil to dryness. Note the temperature of the first drop. Collect 60 drops of distillate per test tube. You will need 5 test tubes, thus five…Define Distillation?

Arrange the following steps based on the order they occur in a distillation process:I. The vapor condenses with the aid of flowing cold water in the condenserII. The liquid is collected in the receiving flask, removing the first 1 mL of the distillateIII. The mixture is heated in the distilling flask while simultaneously monitoring the temperatureIV. The more volatile component evaporates and passes through the three-way connector2.
