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 - Subjective questions on Solubility of solids in liquids

                                                                    Subjective Questions 1.  Why is benzene soluble in toluene but not in water? Sol.  “ Like dissolves like”. Benzene and toluene are non-polar; H 2 O is polar. 2 . Explain, why solute-solute, solvent-solvent and solute-solvent interactions are important in determining the extent to which a solute dissolves in a solvent? Sol : In the dissolution process, solute – solute, solvent – solvent interactio n overcom e  and solute – solvent interactions are overcome and solute – solvent i nteractions are established. The solubility of a solute thus, depends on the strength of new solute – solvent interactions relative to the strengths of solute – solute and solvent – solvent interactions. 3. Indicate the type of solute – solvent inter mole...
