Filo · Accepted Answer

The correct option is (c).On dissolving chalk powder in water,a suspension is obtained.The mixture is stirred for sometime to ensure the uniform dispersion of chalk powder in water.Suspension is a heterogeneous mixture of particles from which the particles are settled down with time.Chalk powder does not dissolve in water at all.It just forms suspension in water and after some time settles down under the influence of gravity.
