Question 1

How can you separate a mixture of liquids?

Answer 1

Using fractional distillation

Question 2

What do you do first? (Put)

Answer 2

Put your mixture in a flask and stick a fractionating column on top. Then you heat it

Question 3

What will the different liquids all have?

Answer 3

Different boiling points - will evaporate at different temps

Question 4

Which liquid will evaporate first?

Answer 4

The one with the lowest boiling point

Question 5

What happens when the temp on the thermometer matches the boiling point of this liquid?

Answer 5

It will reach the top of the column

Question 6

What will liquids with higher boiling points do?

Answer 6

Might also start to evaporate

Question 7

Where is the column cooler?

Answer 7

Towards the top

Question 8

Because they are cooler, they will only get part of the way up before…

Answer 8
