✦ Synopsis

The kinetics and mechanism have been investigated in the Cd(II)/Cd(Hg) system in 2 M NaClO, + 1 M HC104, at 25 t 0S"C. The galvanostatic single-pulse method has been used. The value of double-layer capacity, exchange current density, as also the a value, k, and the partial reaction order of each of the component which takes place in the reaction, have been determined on the grounds of different kind of anions in the solution. The two-step single-electron exchange mechanism has been suggested, as also the one-step exchange reaction in combination with the reaction of disproportionation.
