## Equation (3) can easily be derived from the condition of equality of electrochemical potentials of specifically adsorbed ions at the inner Helmholtz plane and in bulk solution, assuming the surface activity of ions is expressed as zel and the bulk activity as inc.

✦ Synopsis
Formulae (1) and (2) differ from eqn. (18) in ref. 1 by the sign. The reason is that the signs of the charge components are considered, so that e = -51-e~-e~. Differentiation of this equation by 51 at e=const, gives * Indeed, at m=l we have the pure solution of K1A and the isotherm parameters fl and B, O naturally, can not depend on the concentration of the salt, KxA.

The adsorption of formate and acetate ions on mercury electrodes was studied at 25°C from constant ionic strength solutions of composition XM HCQQNa+(O.S-x) M NaF and rcM CH,CQQNa + (0.5 -K) M NaF, respectively. The adsorption characteristics of the two anions are compared with previous results in s
The adsorption bhaviour of &PO; anions on mercury has previously been analysed from capacitance-potential relations at the interface of mercury with K&PO,. It is not possible to determine unambiguously the adsorption characteristics of I&PO, ions from siagle salt solution experiments because of the
The adsorption of Br-anions has been studied from propylene carbonate solutions of low ionic strength (0.16 h4) at mercury. A maximum on the capacity curve is observed at low Br-ion concentration, a result which is unusual for strongly adsorbed ions. A new method of analysing the interfacial thermod
