Study Notes
Solutions
- Examples include salt water and rubbing alcohol.
- Solutions consist of small, evenly spaced particles.
- They do not scatter light, which distinguishes them from colloids and suspensions.
- Can be separated through distillation.
Colloids
- Examples include milk, gelatin, and muddy water.
- Colloids contain medium-sized particles that remain dispersed.
- They do scatter light, leading to the Tyndall effect.
- Separation may still be possible through processes like distillation.
Suspensions
- Examples include dust in air and oil in water.
- Suspensions are characterized by large particles that may settle over time.
- They scatter light, making them appear cloudy.
- Can be separated using filtration methods.
Comparison of Solutions, Colloids, and Suspensions
- Solutions have very small, unscattered particles; remain homogeneous and stable.
- Colloids have medium particles that scatter light and typically display a cloudy appearance.
- Suspensions have large particles that can settle out of the mixture, leading to separation over time.
