WebThe intensity of Tyndall scattering increases with increase in the size of colloidal particles as well as the concentration. Starch sol is a lyophilic sol. Hence the sol particles are very small and highly solvated. There is almost no difference in the refractive indices of dispersion medium (water) and dispersed phase (starch). WebSuch kinds of sols are known as lyophobic sols. These kinds of colloidal solutions always carry some charge on them. All the particles of a given colloidal system have like charges because of which they don’t combine together and settle down. This is the main cause of the stability of colloids. WebIf water is used as the dispersion medium, lyophilic sols are called hydrophilic sols. Starch, gum, gelatin, egg albumin etc. are examples of lyophilic sols. Starch Sol.
