Coalescence of bubbles is important in many chemical, environmental and biological processes. This monograph presents coalescence of air bubbles in single- and multi-component aqueous solutions of alcohols and nonionic surfactants. Adsorption of these compounds at air-water interface was studied by measuring the equilibrium surface tension of the aqueous solutions. The role of electrostatic double layer, hydration and steric forces on coalescence was investigated. It was found that the stability of the thin aqueous film depends on the subtle interplay of intermolecular and surface...
