Study Notes
Solutions
- A solution is a homogeneous mixture of two or more substances, where one substance (solute) dissolves in another (solvent).
- Solute: The substance that dissolves. Examples include salt in water.
- Solvent: The substance that does the dissolving. Examples include water.
Solubility
- Solubility is the ability of a substance to dissolve in a solvent at a specific temperature and pressure.
- Concentration refers to the amount of solute dissolved in a specific amount of solvent.
- High concentration = "concentrated" solution (lots of solute)
- Low concentration = "dilute" solution (small amount of solute)
- Saturation occurs when a solution has dissolved the maximum amount of solute at a given temperature. Any further solute added will not dissolve.
Factors Affecting Solubility
- Temperature: Generally, solubility of solids in liquids increases with temperature. For gases, higher pressure increases solubility.
- Pressure: Mainly affects the solubility of gases. Increased pressure increases solubility.
- Nature of Solute and Solvent: Some substances dissolve better in certain solvents. (e.g., salt in water, oil in vinegar).
Types of Solutions
- Solid in Liquid: Sugar in tea
- Gas in Liquid: Carbon dioxide in soda
- Gas in Gas: Air
- Liquid in Liquid: Alcohol in water
Dilution
- Diluting a solution means adding more solvent to decrease the concentration of solute.
Universal Solvent
- Water is called the universal solvent because it dissolves more substances than any other liquid.
