To know the difference between reversible and irreversible changes
Important facts to learn:
- some materials will dissolve in liquid to form a solution, and it is possible to recover a substance from a solution.
- Understand the difference between reversible and irreversible changes
Some materials (solutes) will dissolve in liquid (solvents) to form a solution. The solute can be recovered by evaporating off the solvent by heating.
