Knowledge and Understanding 1. Explain why mass is conserved when a solution is formed and describe a simple experiment to prove it.
2. Why do you think that only a certain amount of solute can dissolve in a fixed volume of solvent?
3. Give examples of three different mixtures that can be separated by filtration. 4. What happens to the water when you heat a mixture of salt and water above 100o
6. How does a Liebig condenser work? 7. Give three mixtures that could be separated using a Liebig condenser.

Thinking and Investigating 1. Do you think increasing the temperature of a solvent would change the amount of solute it
could dissolve? Describe a simple experiment to investigate this.
2. Can distillation only be used to separate soluble solids and liquids? Find out some other uses of distillation.
