Electrochemistry of fuming sulphuric acids : III. Mechanism of the cathodic reactions on platinum
The cathodic potential-decay process on platinum electrodes in oleums has been investigated by means of a rotating disk. The non-stady parameters are compared with those already reported under steady-state conditions. Both results are discussed in terms of a general reaction mechanism comprising var...

description |
The cathodic potential-decay process on platinum electrodes in oleums has been investigated by means of a rotating disk. The non-stady parameters are compared with those already reported under steady-state conditions. Both results are discussed in terms of a general reaction mechanism comprising various consecutive as well as alternative steps, considering that the main cathodic product is sulphur dioxide. The SO<sub>3</sub>-containing species acts as a depolarizer by reacting with hydrogen atoms adsorbed on the electrode surface. |
