GCSE Chemistry Distillation Practical

1

Set up the apparatus as shown in the diagram. Add a few anti-bumping granules to the ink in the boiling tube

2

Adjust the Bunsen burner so that the air hole is slightly open, giving a gentle blue flame

3

Very carefully heat the ink so that it simmers gently. If it starts boiling, immediately move the Bunsen burner away

4

Collect the distillate in the test tube and record the temperature of the vapour being distilled off

5

Stop heating once you have collected about 1cm depth of distillate, taking care to avoid suck-back

6

While the apparatus is cooling, confirm the identity of the distillate by adding a small spatula of anhydrous copper sulfate to the test tube. Record your observations
