1. Understanding Solutions

2. What is a Solution? A solution is a well-mixed mixture. A solvent dissolves other substances. Example: water A solute is being dissolved. Example: salt

3. Concentration Dilute Solution – small amount of solute dissolved in the solvent Concentrated Solution – a lot of solute dissolved in the solvent.

4. Solubility Solubility is the measure of how much solute can dissolve in a solvent at a given temperature. Saturated solution – no more solute can dissolve

5. Unsaturated solution – can dissolve more solute Supersaturated – more dissolves than predicted

6. Factors Affecting Solubility Pressure – the higher the pressure, the more that can be dissolved Like dissolves like – the more similar the materials the easier they dissolve Temperature – the higher the temperature, the more that can be dissolved.
