Kinetic study of the first one-electron stage of indium ionization

Using the method of rotating disk electrode kinetics of the stage of In particle transfer through the phase interface electrode-electrolyte is studied. The investigations are carried out in the electrolyte of the composition xMHClO4+(3-x)MNaClO4, where x=(3x10-3-3)M at 22 deg C. The region of the stage actual kinetics is found and anodic coefficient of transfer of the stage is determined. The stage studied obeys the theorem of delayed discharge. The established independence of the stage rate of hydrogen ion concentration proves that the chemical reaction of indium intermediate hydrolized particles formation takes place in subsequent stages of indium dissolution
