It does not separate upon standing ecause of its small particle size (Ex. salt & water). heterogeneous mixture w/particle size of 1-100nm that looks like a homogeneous mixture (Ex: Milk, fog, jello). colloidal dispersions made of two liquids (Ex; soap & water, detergent & water) scattering of light caused y colloid particles seen in a eam of light such as dust in air in a "shaft" of sunlight chaotic movement caused y collisions of dispersed colloidal particles with water molecules, preventing the colloid from settling
