The concentration of a solution tells us how much solute is present in a given amount of solution.
| Type | Amount of Solute |
|---|---|
| Dilute | Less solute |
| Concentrated | More solute |
| Saturated | Maximum solute dissolved |
| Unsaturated | Less than maximum |
A saturated solution has dissolved the maximum amount of solute possible at a given temperature.
The amount of solute in a saturated solution at a particular temperature = Solubility
Most solids: Higher temperature → Higher solubility
Concentration = (Mass of solute / Mass of solution) × 100
Concentration = (Mass of solute / Volume of solution) × 100
Concentration = (Volume of solute / Volume of solution) × 100
