1

What is meant by a 'saturated solution'

A solution containing the maximum amount of solute dissolved into it.

There is always some undissolved substance in the container.

2

What is meant by 'solubility'?

How well a solute dissolves into 100 g of water

3

What units do we measure solubility in?

g/100 g of water

4

Which is more soluble: salt or sugar?

Sugar

5

How do you know that sugar is more soluble than salt?

More sugar can dissolve into 100 g of water than salt.

6

What is meant by an 'insoluble' solute?

A solute that will not dissolve in water.

7

Give an example of an insoluble solute.

Chalk

Sand

8

How does temperature affect solubility?

The higher the temperature, the more soluble a substance becomes.

9

Does the solubility of different substances increase at the same speed?

No some substances do not become much more soluble. e.g. salt.
