The simultaneous measurement of current, mass, motional resistance and absorbance magnitudes allows the electrochemical cation insertion process to be explained during successive voltammograms around the Prussian Blue ⇄ Everitt's Salt system in CsCl aqueous acid solutions. Two different ways for the entrance of cesium to the porous structure of Prussian Blue have been observed. Firstly, Cs+ is spontaneously absorbed as CsCl into the interstitial cluster of water of the channels formed by the Fe(II)low spinCNFe(III)high spin structural units of the crystal. This chemical absorption involves a spontaneous substitution of inner water molecules of the interstitial water cluster. Finally, Cs+ can act as a counter-ion during electrochemical stabilization process of Prussian Blue by means of successive voltammograms. [-]
