Study Notes
Mixtures
- A mixture is a combination of two or more substances, each retaining its properties.
- Mixtures can be separated by physical methods.
- Mixtures can be homogeneous or heterogeneous.
Solutions
- A solution is a transparent mixture of a solute dissolved in a solvent.
- The solute and solvent remain evenly distributed and don't separate when left to stand.
Colloids
- A colloid is an opaque mixture of tiny particles suspended in another substance.
- These particles are too small to see with the naked eye.
- Unlike suspensions, colloids do not separate when left to stand.
Mechanical Mixtures
- A mechanical mixture is a heterogeneous combination of substances.
- The components can be easily distinguished.
Suspensions
- A suspension is a heterogeneous mixture of a solid and a liquid.
- Particles in suspensions settle out over time.
- Suspensions can be separated by filtering.
Emulsions
- An emulsion is a heterogeneous mixture of two liquids.
- Emulsions separate when left to stand.
Solutes and Solvents
- A solute is the substance that dissolves in a solvent.
- A solvent is the substance that dissolves the solute.
- Together they form a solution.
