The adsorption of azide ions on mercury electrodes has been studied from constant ionic strength solutions of composition χ M NaN3 + (μ–χ) M NaF with μ = 0.25 and 0.5. Double layer parameters were obtained by taking into account the change in activity coefficients with solution composition. The results were analyzed together with those reported previously for μ = 0.95, recalculated to take into account the change in activity coefficients. The influence of the ionic strength on the amount adsorbed, the properties of the inner layer, and the parameters of an adsorption isotherm for azide anions are discussed in terms of the electrostatic model of the double layer.

The kinetics of oxidation of arsenic(III) by hexachloroiridate(IV) at lower acid concentrations and at constant ionic strength of 1.0 mol dm-3 have been investigated spectrophotometrically. A first-order reaction in [IrCl62-] and fractional order with respect to arsenic(III) have been observed. A kinetic evidence for the formation of an intermediate complex between the hydrolyzed arsenic(III) species and the oxidant was presented. The results showed that decreasing the [H+] is accompanied by an appreciable acceleration of the rate of oxidation. The activation parameters have been evaluated and a mechanism consistent with the kinetic results was suggested.
