A suspension is a heterogeneous mixture in which solid particles are dispersed in a liquid but do not dissolve. The particles are visible to the naked eye and may settle down over time.

Key Properties of Suspensions:

Heterogeneous Mixture :- The components are not uniformly mixed throughout.
Visible Particles :- The particles are large enough to be seen without a microscope.
Settling of Particles :- The suspended particles settle down over time if left undisturbed.
Can Be Separated by Filtration :- Since particles are large, they can be easily filtered out using filter paper.
Does Not Show Tyndall Effect (in some cases) :- Suspensions may scatter light, but not as clearly or consistently as colloids.
Unstable :- Suspensions are not stable; particles settle unless the mixture is stirred or shaken.
Opaque Appearance :- Suspensions often appear cloudy or opaque due to undissolved particles.

Examples of Suspensions:

Mud in water
Sand in water
Chalk powder in water
