What is a suspension in chemistry?

A suspension is a heterogeneous mixture where solid particles larger than 1000 nm are dispersed in a liquid but settle on standing.

• Opaque, unstable, particles separated by filtration.
• Does not show Tyndall effect clearly.

Examples: Chalk in water, muddy river water, sand in water.

A suspension contains large dispersed particles that make the mixture cloudy and settle out over time without stirring.
