Study Notes
Solutions and Solubility
- Solution: A homogeneous mixture of two or more substances.
- Solvent: The substance that does the dissolving (usually a liquid).
- Solute: The substance that gets dissolved. Examples include sugar and salt.
- Aqueous Solution: A solution where water is the solvent.
- Solubility: The ability of a substance to dissolve in another and form a solution.
- Saturated Solution: A solution that cannot dissolve any more solute at a specific temperature.
- Unsaturated Solution: A solution that can dissolve more solute at a specific temperature.
- Supersaturated Solution: A solution containing more dissolved solute than a saturated solution at the same temperature.
- Hydrogen Bonding: A weak bond between molecules, where a hydrogen atom in one molecule is attracted to another atom in another molecule. This plays a critical role in dissolving some substances.
- Hydration: When water molecules surround and interact with a solute, helping it to dissolve. This is exemplified when salt dissolves in water.
- Rate of Dissolving: The speed at which a solute dissolves in a solvent. Factors like stirring affect this rate.
Concentration and Measurement
- Concentration: The amount of solute present in a solution compared to the amount of solvent.
- Concentrated: A solution with a high amount of solute dissolved in a relatively small amount of solvent.
- Diluted: A solution with a low amount of solute in a relatively large amount of solvent .
- Percent (m/v): A concentration measurement. Grams of solute per 100 milliliters of solution.
- Percent (m/m): Mass of solute per 100 grams of solution.
- Percent (v/v): Volume of solute per 100 milliliters of solution.
- Parts Per Million (ppm): Used to express very small amounts of solute in a solution.
- Parts Per Billion (ppb): Similar to ppm, but for even smaller amounts.
- Molar Concentration: The amount of solute in moles per liter of solution.
Solubilty Characteristics
- Soluble Compound: A compound that dissolves in water.
- Insoluble: A compound that does not dissolve in water.
