1. A suspension is a heterogeneous mixture of a finely distributed solid in a liquid. The solid is not dissolved in the liquid, as is the case with a mixture of salt and water.
2. The difference between a solution and a suspension is in the particle sizes involved. A solution is a mixture of ions or molecules (very, very small). Solutions are transparent, meaning that you can see through them. A suspension has bigger particle sizes and so it may look cloudy or murky.
3. Gravity is able to pull the visible particles in a suspension down if undisturbed, and they will stay that way unless being actively mixed.
4. General Characteristics and Properties of Suspension
-Suspensions are a heterogeneous mixture of two or more substances. Particles of the solute do not dissolve in the solvent rather they remain suspended in bulk throughout. ... It does not scatter light when particles are settled because in this case suspension breaks.
5. Chalk suspended in water.
