Definition: a two phase system consisting of a coarse dispersion finely divided insoluble solids dispersed in a liquid. DR AMINA TARIQ. BIOCHEMISTRY. COLLOIDAL STATE. Colloids are a type of mixture. It is composed of two phases: . Dispersion medium and dispersed phase.. Colloids are the mixtures in which dispersion . phase. Can you name an example of a colloid?. Colloids. are mixtures with particles intermediate in size between solutions and suspensions (particle size 1 nm to 1000 nm). You cannot see the individual particles.. Colloids and suspensions are heterogeneous . mixtures. Suspensions and Colloids. Suspensions and colloids are NOT solutions. . Suspensions. : The particles are so large that they settle out of the solvent if not constantly stirred.. SUSPENSIONS. 1. SUSPENSIONS. 2. . SUSPENSIONS:. Definition. A Pharmaceutical suspension is a coarse dispersion in which internal phase (. therapeutically active ingredient. ) is dispersed uniformly throughout the external phase.. Solutions and Other Mixtures.

The first involve selective adsorption of a particular ionic species present in solution.. Second : charges on particles arises from ionization of groups (such as COOH) that may be situated at the surface of the particles..
