Paper 1: Distilation

Question 1

What are the 2 types of distillation?

Answer 1

Simple
Fractional

Question 2

What can you use simple distillation for?

Answer 2

To separate a solvent from a solution

Question 3

What happens is simple distillation when the solution is heated?

Answer 3

Solvent boils
Solvent vapour passes into the condenser
Vapour is Cooled and condensed back into liquid state

Question 4

What can you used fractional distillation for?

Answer 4

To separate a liquid from a mixture of other liquids with similar boiling points

Question 5

What happens when the mixture is heated in fractional distillation?

Answer 5

Mixture boils
Hot vapour rises up the fractionating column
Vapour condenses when it hits the cool surface of the column and drips back
Fraction with lowest boiling point reaches top first
Vapour passes into the condenser
