A suspension is a type of heterogeneous mixture in which solid particles are dispersed throughout a liquid without dissolving in it. The particles in a suspension are larger than those in a solution, and they can be seen under a microscope. Suspensions are non-homogeneous systems in which solids are suspended throughout the bulk of the medium. The particles in a suspension are large enough to settle down due to gravity over time.
An example of a suspension is a mixture of mud and water. If we take a glass of water and mix mud in it, it will form a heterogeneous mixture. After some time, we will observe that particles of mud settle down due to gravity.
In summary, a suspension is a type of heterogeneous mixture in which solid particles are dispersed throughout a liquid without dissolving in it. The particles in a suspension are larger than those in a solution, and they can be seen under a microscope. An example of a suspension is a mixture of mud and water.
