Abstract
It is shown that the commonly accepted relation ΔΠ = ∫0ψo for the increase in surface pressure resulting from the charging of a monolayer is not general. The surface pressure increase also includes a term relating to the change of the " non-electrostatic " contribution to the surface free energy. An important part of this additional term originates in the fluctuation or "self-atmosphere" electrostatic potential at an ion in the monolayer and may also be described as the "discreteness-of-change" contribution. The use of two-dimensional equations of state for ionized films as a way of investigating the properties of the ionic double layer is briefly considered.
