Key Stage 2
Meaning
A solution is a mixture where a substance is dissolved in a liquid.
About Solutions
- For most solutions the liquid is water.
- Some solids dissolve in water to make a solution.
- Once a substance is dissolved in water it is often not possible to see it anymore.
- If a substance has a colour before it is dissolved the solution be will that colour.
Examples
Salt | Sugar |
Salt dissolves in water to make a solution called Brine. | Sugar dissolves in water to make a solution. |
Key Stage 3
Meaning
About Solutions
- Solutions are usually made of liquid that is known as a solvent and a solid which is known as a solute.
- When a solute dissolves in a solvent it becomes a solution.
- Some solutions are a mixture of two solvents, for example water and ethanol.
Examples
Brown sugar is the solute. | Water is the solvent. | The solute dissolves in the solvent to make a solution. |
Copper Sulphate is the solute. | Water is the solvent. | The solute dissolves in the solvent to make a solution. |
Separating Solutions
- The solute and solvent can be separated by distillation.
