What is the difference between suspension, emulsion and colloidal solution?

Emulsion is a fine dispersion of minute droplets of one liquid in another in which it is not soluble or miscible

Suspension is a mixture in which particles are dispersed throughout the bulk of a fluid

        Colloid is  a homogeneous, noncrystalline substance consisting of large molecules or ultramicroscopic particles of one substance dispersed through a second substance

A suspension is a heterogeneous mixture of solid particle in carrier liquid. It is not dissolved it is suspended. The emulsion is the mixture of two or more immiscible liquids. E.g. Water and oil, soap and water. A colloidal solution is the mixture  of sub micronic particles in carrier liquid.The particles are kept in suspension through brownian motion.

An emulsion is a mixture of two or more liquids that are normally immiscible

Emulsions are part of a more general class of two-phase systems of matter called colloids

substance in which one substance of microscopically dispersed insoluble particles is

suspended throughout another substance. Sometimes the dispersed substance alone is called the colloid

suspension is a heterogeneous mixture containing solid particles that are sufficiently large for sedimentation.

A colloid is a substance in which microscopic particles are dispersed in a medium, but are not dissolved in it. If left undisturbed, the dispersed particles will not settle or form sediment. Pumice could be an example of a colloid: particles of air dispersed in solid stone.An emulsion is a particular type of colloid, referring to microscopic particles of liquid dispersed in another liquid. Milk could be an example of an emulsion: lipophilic butterfat particles dispersed in a water-based medium.A suspension is similar to a colloid except that the dispersed particles tend to be larger and will eventually settle or form sediment. Sand in water could be an example of a suspension: if shaken then the sand will disperse in the water, but if left alone it will settle at the bottom.
