This type of sulphur is prepared by passing hydrogen sulphide through a cooled saturated solution of sulphur dioxide in water, or by adding a solution of sulphur and alcohol in water. Colloidal sulphur is soluble in carbon disulphide. It is used in medici..

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 solution, but they co..

Preparation of Colloidal Sols - For the preparation of lyophilic and lyophobic sols different methods are used..

Henry bought 4 gallons of paint. After painting his house, he was left with 1 gallon of it. Which expression represents the gallons of paint used by him? => - 4 = 1 or 4 - = 1 or + 4 = 1 or - 1 = 4..

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 consists of..

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..
