what are suspensions

A suspension is a type of heterogeneous mixture in which solid particles are spread throughout a liquid without dissolving in it). The particles in a suspension are large enough to be visible to the naked eye, and they do not pass through a filter paper. Suspensions are unstable, and the particles settle down after some time. The diameter of particles in a suspension is generally between 500-1000 nm. Some common examples of suspensions include muddy water, milk of magnesia, sand particles suspended in water, flour in water, slaked lime for whitewashing, and paints in which dyes are suspended in turpentine oil. Suspensions are different from solutions and colloids. In a solution, the solute is dissolved in the solvent, while in a colloid, the particles are smaller and do not settle). Suspensions can be separated by filtration.
