| Abstract: | The electrochemical dissolution of palladium in a number of aqueous solutions containing ClO4, Cl?, I?, has been investigated using current-potential and impedance-potential measurements. It is concluded that during active dissolution, from Cl? containing solution, the reaction to form a soluble complex PdCl2 is inhibited by a PdOH layer and passivated by PdO. Dissolution in I? containing solutions proceeds by a different mechanism. |
