Question

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.

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.

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!

Answer 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.
