Applications of Colloids

Science > Chemistry > Colloids > Applications of Colloids Natural Applications of Colloids: Blue Colour of Sky: When the light is incident on particles whose size is smaller than the wavelength of light, it is scattered. The blue colour of the sky is due to the scattering of light by small particles (dust particles along […]

Science > Chemistry > Colloids > Gels A gel is a colloidal system in which the dispersed phase is liquid and the dispersion medium is solid. e.g. when warm sol of gelatin is cooled, it sets to a semi-solid mass which is a gel. Jellies, jams, curd, butter, shoe polish, etc. are gels. The interior […]

Science > Chemistry > Colloids > Associated Colloids (Micelles) In thisarticle, we shall study bout associated colloids :micelles). Multimolecular Colloids: Multimolecular colloids are those systems in which the dispersed phase particles are aggregates of many atoms or molecules. The particles in this colloidal solutions are held together by van der Wall’s forces. e.g. gold sol particles […]

Science > Chemistry > Colloids >Types of Colloidal Solutions In this article, we shall study types of colloidal solutions (systems) on the basis of states of the dispersed phase and dispersion medium, the interaction between the dispersed phase and dispersion medium, and on the number of atoms and molecules in a colloidal particle. Types of […]
