Safety Note
Goggles must be worn at all times during this
experiment. Use extreme caution when working with fire and the
flammable products formed in this lab. Use hot mitts when handling hot
objects. please review and follow the safety guidelines at the beginning
of this volume.
Procedure
1. Set up the distillation apparatus as shown in Figure 2. As you do,
keep these points in mind:
a. The two test tubes should be connected to two ring stands with
utility clamps.
b. The test tube that will be heated should be placed horizontally or
at an angle as shown in Figure 2. It will contain the stopper with
a single hole. This test tube will be positioned over a Bunsen
burner.
c. The test tube that will collect the products will be placed
vertically and have the stopper with two holes.
d. The long piece of L-shaped glass tubing will connect the two test
tubes.
e. The short piece of L-shaped tubing will be placed into the second
hole of the vertical test tube.
2. Fill the horizontal tube about one-fourth full with wood chips.
3. Light the Bunsen burner with a flint striker and place it directly below
the wood chips in the test tube.
4. Heat the wood chips thoroughly so that they become completely
charred.
5. Light a match in the mouth of the small L-shaped tube. Record your
observations in your science notebook.
