Study Notes
Concentration of Solutions
- A solute dissolves in a solvent to form a solution.
- Water is a common solvent, used to dissolve solids like orange drink crystals.
- Concentration refers to the amount of solute dissolved in a specific amount of solvent or solution.
- A solution with a low concentration is called dilute.
- A solution with a high concentration is called concentrated.
- The more solute, the more concentrated the solution, and often the stronger the taste.
Solubility
- Solubility is a substance's ability to dissolve in a solvent (like water)
- Not all substances dissolve in water.
- Some substances are soluble in water, meaning they dissolve.
- Some substances are insoluble in water, meaning they do not dissolve
Saturated and Unsaturated Solutions
- A saturated solution contains the maximum amount of solute that can dissolve in a given amount of solvent at a specific temperature.
- Any more added solute will not dissolve and will settle at the bottom.
- An unsaturated solution can dissolve more solute.
- Solubility depends on temperature; usually more solute can dissolve in warmer solvents.
Supersaturated Solutions
- A supersaturated solution holds more solute than is usual for a saturated solution at a given temperature. This is unstable.
- Adding a "seed crystal" (a small crystal of the solute) can cause the excess solute to rapidly crystallize out of the solution.
