a) The equipment you would use for carrying out a simple distillation at reduced pressure (i.e. under vacuum)

b) the equipment you would use for carrying out a simple distillation at atmospheric pressure.

The equipments are stated but I don't know which one is to use for each question!

Thermometer
Thermometer adapter
still head
condenser
adapter
receiver
boiling flask
heating mantle


Thanks!

  1. Simple distillation at atmospheric pressure. These differ little from diagram to diagram but the parts are labeled.

    Here are images of vacuum systems and they differ a little from diagram to diagram.

    I don't see a source for vacuum listed in the equipment list you show. And "adapter" listed separately don't tell me much. I think almost all of the items used for a simple atmospheric distillation are also used for a vacuum distillation with exceptions that for vacuum you must have a vacuum source AND for vacuum you must have the system closed and not open to the atmosphere.
