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.
