suspensions and colloids

True Solutions, Suspensions and Colloids - 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..

Colloids - 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 appea..

Colloidal solution or colloidal state or colloidal dispersion, represent an intermediate kind of a mixture between true solution and suspension. The size of a colloidal particle lies roughly between 1-100 nm. Colloids are also a two-phase ..

In mechanical dispersion, the coarse suspension of the substance is ground in a colloid mill, a ball mill or an ultrasonic disintegrator. The colloid mill consists of two metal discs, close together and rotating at high speed (7000 revolutions per minute) in opposite ..

Introduction - The different kinds of micromolecules and macromolecules that we have studied so far occur in the cell dissolved in solution or as suspensions in a colloidal state. Alternatively, they may be assembled into subcellular components like cell membrane, cytoplasm and ..

. Catalysis involves reactions where catalysts are used. Catalysts are used to accelerate the rate of reaction. Catalysts accelerate the rate of reaction by providing an alternate reaction pathway in which the activation energy is lower. Homogenous catalysis involves catalysts which are of the same..
