To obtain a sample of water from sea-water using simple distillation

Procedure:

  1. Set up as shown above.

  2. Part C is called a condenser; it has an outer tube which carries cold water which causes the water vapour passing through the inner tube to condense back into a liquid.

  3. Cold water goes in through D and out through B.

  4. The round-bottom flask above the Bunsen burner contains sea-water.

Result:

The water evaporates from the round-bottom flask, travels through the condenser where it condenses and flows into the beaker as pure water.
