This lecture discusses the behavior of soils with oxide surfaces, focusing on variable charge arising from ionization of surface reactants. It covers amphoteric behavior of hydroxide surfaces, pH 'edges' for cation and anion sorption, and the Diffuse Double Layer Model. The lecture also explores surface reactions, apparent reaction constants, and the calculation of surface charge. Various models and assumptions for surface reactions are presented, along with the impact of surface charge on macroscopic soil behavior.
