Flashcards in C2.1.5 - Distillation Deck (10):
1

What does simple distillation do?

Separate a solvent from a solution

2

What does simple distillation rely on?

The solvent having a lower boiling point than the solute

3

What is simple distillation good for?

Purifying a solvent

4

How does simple distillation work?

The solution is heated until the solvent evaporates. The solvent then goes to the condenser and condenser into a new container and becomes pure

5

Name all the equipment used in simple distillation

Thermometer
Condenser

6

How is the condenser kept cool?

By a constant cold water flow

7

What does fractional distillation do?

It separates 2 or more liquids

8

What does fractional distillation rely on?

All the substances having different boiling points

9

How does fractional distillation work?

Both liquid substances evaporate into the fractionating column. When they condense, the temperature increases, until 1 of the substances fully evaporate while the other drops back, in purity

10

Why is the fractionating column good for fractional distillation?

It has a large surface area on which the vapours can continually condense.
