Molecular formula :
nature : the size of the 0.1 ~ 0.001 µ m of tiny particles dispersed in another medium formed by heterogeneous highly decentralized from the Department. It is droplets or solid particles dispersed in a gas, can also be bubbles and droplets or solid particles dispersed in liquid or solid matter of a variety of medium. Ephemeral, in the fog, emulsion, the foam. The characteristics of colloidal particles are dispersed over large surface area, and so they have a series of special nature, such as Brownian motion, Mr Tudor Fall effect, electrokinetic phenomena, and Dynamic Stability Coalescence not stability.
