Colloidal State



Finely divided particles of any substance with diameters lying within 1 - 200 nm dispersed in any medium constitute what we term a colloidal system. 
A colloidal system is thus a two phase system consisting of a continuous phase or dispersion medium in which extremely minute particles, lying within the colloidal range, of second substance termed as discontinuous phase, are suspended.
In this chapter you learn about classification, preparation and properties of colloidal solutions which are explained in the following video. Have a look !!!!

Solutions Chapter - Types of solutions

Introduction In normal life we rarely come across pure substances. Most of these are mixtures containing two or more pure substances. Their utility or importance in life depends on their composition. For example, the properties of Brass (mixture of Cu and Zn) are quite different from those of German silver (mixture of Cu, Zn and Ni) or Bronze (mixture of Cu and Sn); 1 ppm of Fluoride ions in water prevents tooth decay, while 1.5 ppm causes the tooth to become mottled and high concentrations of fluorides ions can be poisonous (for example, sodium fluoride is used in rat poison); intravenous injections are always dissolved in water containing salts at particular ionic concentrations that match with blood plasma concentrations and so on. Solution  - What does it mean? A true solution is defined as a perfectly homogeneous mixture of two or more substances   (called as components)  having uniform properties throughout and the composition of which may vary within limits. The su...
