The origin of the negative charge at water/air interface was proved to be not only specific adsorption of OH ions but that of HCO and/or CO ions in the previous study [1]. To determine which anionic species is primarily responsible for the surface charge, the surface density of ions in the Stern layer is numerically evaluated from foam-film thickness of aqueous solutions of NaHCO and Na CO . Equilibrium thickness (equivalent thickness at equilibrium) of the foam films formed from aqueous solutions of NaHCO a
