Abstract
A NUMBER of attempts have been made to determine the adsorption of surface-active substances from solutions containing salts, by the use of the Gibbs' equation, in the form where dρ is the variation of the surface tension caused by a change dμb(= RTd log αB) in the potential of the substance B.1 The complete equation of Gibbs as applied to a ternary system A-B-S is but if the dividing surface up to which the solution is supposed to be perfectly homogeneous is defined so that T = 0, this becomes. This equation reduces to (1) when the variation of μs is negligible in comparison with that of μB. This will be the case when the concentration of B is very small, but will cease to hold at greater concentrations.
