Define the following terms:
(i) Sorption
(ii) Tyndall effect
(iii) Electrophoresis

Explanation

(i) Sorption is a physical and chemical process by which one substance becomes attached to naother specific cases of sorption are treated in the following way:
Asborption the incorporation of a substance in one state into ajotehr of different state (e.g liquied being absorbed by a solid or gases being absorbed by liquid )
Adsorption the physical adherence or bonding of ions and molecules on to the surface of anothe phase (e.g reagents absorbed to solid catalyst surface)
Ion exchange an exchange of ions between two electrolytes or between an electorlyte solution and a complex
(ii) Tydall effect : The phenomeonon of scattering of light by colloidal particles as a result of which the path of beam becomes visibles is called tyndall effect
(iii) Eelctrophoroesis : when electric potential is applied across two platinum electrodes dipping in a colloidal soluton the collidal particlus move towards one or the other electrode .The movement of colloidal particles under an appied electric potential is called electrophoresis
