Amalgam electrode behaviour

This equation may take a variety of forms depending upon the behaviour of the oxidised and reduced species at the electrode. The version presented here is applicable to a situation where the oxidised species is the only species in the solution and this species is being reduced at a cathode where the reduced species either goes into solution or forms an amalgam with mercury. This equation is then directly relevant to most of the applications of dc polarography. Consider the Ilkovic equation applied to the reaction ...
