โฆ Synopsis
Mass transfer at vertical plates with gas spar&q obeys formally the same correlation as mass transfer in turbulent natural convection due to concentration or remperature differences. A model is presented which allows a theoretical interpretation of this result.

To elucidate the mechanism af the mass transfer at a gas evolving electrode, the thickness of the diffusion layer 6 has been determined as a function of the volume rate of the gas evolution u, for both hydrogen and oxygen evolving electrodes in alkaline solution. The effect of electrode material, al
The effect of H2 and O2 evolution on the mass transfer coefficiem of the reduction of K3Fe(CN)6 and the oxidation of &Fe(CN), at nickel electrodes was studied up to 105 mA/cm2. The relation between the rate of gas evolution and the mass transfer coefficient was found to be: and log K = a + 0.25 log
