types of colloidal solutions

Dispersed phase Dispersed medium Colloidal system Examples Solid Solid Solid sols Coloured glues, gem stones, pearls, some alloys Solid Liquid Sols Paints, gold sol, sulphur sol, starch, proteins Liquid Solid Gels Jellies, cheese butter, hoot ..

It is well known, that solutions are homogenous systems while suspensions are heterogeneous systems, i.e., they consist of more than one phase. In between the extremes of suspensions and solutions lies the colloidal syste..

It is well known, that solutions are homogenous systems while suspensions are heterogeneous systems, i.e., they consist of more than one phase. In between the extremes of suspensions and solutions lies the colloidal system. Colloids appear homogenous like a h..

Types of Colloids - Colloids are characterized a) according to the state of the dispersed phase and the state of dispersion medium. b) nature of interaction between dispersed phase and dispersion medium. c) types of particles of the dispersed phas..

Each of the two phases of a heterogeneous colloidal system i.e., the dispersed phase and dispersion medium, can be in any one of the three physical states of matter. We have eight different types of colloidal solutions (not nine), since a colloidal..

A true solution is a homogeneous solution in which the solute particles have diameters less than 10 - 7 cm. i.e., the solute particles are of molecular dimensions. The particles are invisible even under powerful microscopes. For example, sodium chloride in wa..

Macromolecular colloidal particles are formed when on dissolution in a suitable solvent, the macromolecules have sizes which are in the colloidal range. Naturally occurring macromolecules are starch, proteins and cellulose. Man made macromolecules are polymers such as polyethyl..

In this type of colloids the colloidal particles are aggregates of atoms or small molecules with molecular size less than one nanometer (1 nm). For e.g., gold sol consists of particles of various sizes which are clusters of several gold atoms. Similarly, sulphur sol c..

Colloids have uses in our daily life as well as in various industrial processes. Some of the applications where colloids are present are listed below. 1) Pharmaceutical industry makes use of colloidal solution preparation in many medicines. A wide variety of ..
