LESSON NOTE
Suspensions:
A suspension is defined as a heterogeneous mixture in which the solid particles are
spread throughout the liquid without dissolving in it. A suspension is a heterogeneous
mixture
containing solid particles that are sufficiently large for sedimentation.
Properties of suspensions:
1. A suspension is a heterogeneous mixture.
2. The size of solute particles in a suspension is quite large. It is larger than 100mm
in diameter.
3. The particles of a suspension can be seen easily.
4. The particles of a suspension do not pass through a filter paper. So a suspension
can be separated by filtration.
