Suspensions: Suspension is a heterogeneous mixture in which the solute particles do not dissolve but remain suspended throughout the bulk of the medium.
It is a heterogeneous mixture of small insoluble particles in a solvent.
Particles in suspension are larger than 100 nm in diameter and are visible to the naked eye.
The particles of a suspension scatter a beam of light passing through it and make its path visible.
For example, chalk powder in water, soil particles in water, flour in water, Magnesium in water
