Description
This lecture covers the concepts of surface tension, adsorption on solids, and electrokinetics. It includes discussions on the gas/liquid interface, thermodynamics of adsorption, charged interfaces, DLVO theory, dynamic electrochemistry, and measurements of surface tension. The lecture also delves into the Kelvin equation, contact angle, Wilhelmy plate, Langmuir isotherm, and the BET isotherm for multilayer adsorption. Furthermore, it explores the theory of the diffuse double layer, electrokinetic phenomena like electrophoresis and electro-osmosis, and the DLVO theory of colloid coagulation. The sedimentation potential, streaming potential, and the DLVO theory's critical concentration of coagulation are also discussed.
