    • Abstract

       

      An experimental technique has been developed for obtaining a reproducible platinum electrode surface for measurement of the redoxokinetic potential. The values for ψ for the platinum/ferrous sulphateferric sulphate-sulphuric acid system at room temperature are reported, at frequencies of the A.C. field within the range 50–250 cycles/second. The energy transfer coefficient has been calculated from the measurements of ψ.

      The effects of the circuit resistance, frequencies within the range 50–250 cycles/second and of temperature on the value of ψ have been studied and the results discussed in relation to the theory of the redoxokinetic effect.
