Question

What are the features of suspension?

Answer 1

Hint : A suspension is a heterogeneous mixture that contains solid particles which is sufficiently large for sedimentation. These particles are mainly larger than one micrometer and can be seen or visible through the naked eye. In this heterogeneous mixture solute particles usually do not dissolve although get suspended throughout the bulk of the solvent.

Complete Step By Step Answer:
The important features of the suspension are its heterogeneous nature (it is a cloudy heterogeneous mixture), its particle size (its solute particles are of the size of $100$ nanometers), its visibility (as have mentioned above its particle can be seen through the unaided eye or naked eye ort under a simple microscope. The reason for this visibility is that the particles scatters a beam of light which is passing through it, so the path is visible), sedimentation (as we know its particle size is larger so they have a tendency to settle down while the very fine or lighter particles remain suspended in the medium) and the last feature is separation by filter (the particles which are larger in size can be filtered out from the fluid medium).

Note :
Some common examples of suspension that we see in our day-to-day life includes mud or muddy water in which soil, clay, or silt particles are suspended in the water, flour suspended in water, chalk suspended in water, sand suspended in water, and kimchi suspended on vinegar are all the examples of suspension. The particles of suspension will settle down if left undisturbed.
