Question

What are suspensions? Explain with an example.

Answer 1

A suspension is heterogeneous mixture in which very fine particles (about ${10}^{-5}$ m in size) of solid are dispersed in any medium (liquid or gas). In suspensions, the solute particles are visible to the naked eye and they remain suspended throughout the bulk of the medium. Tyndall effect is observed in such mixtures.

Muddy pond water, smoke coming out of a chimney, chalk-water mixture, coarse lime particles in water are examples of suspension.
