Assume that diagram (a) represents one of the earliest known electroplating systems in which both electrodes are copper and the electrolyte is an acidic solution of copper(II) sulfate. $ Diagram (b) is completely labeled, but diagram (a) has almost no labels. IL.6 Draw the two lines corresponding to the redox couples of water on the Pourbaix diagram of copper (EP(OzHzO) = 1.23 V): Is metallic copper thermodynamically stable in aerated water? In deaerated water at pH = 7? in deaerated water at pH = 0?Ģ months, 3 weeks ago Problem II _ Pourbaix diagram of copperĮxamine Figure $19.1. Calculate the corresponding solubility product: ILS The vertical segment between domains 2 and corresponds to pH of 7.2.
II.4 Determine the slope of the border between domains 1 and 2. IL.3 Identify the species corresponding to each of the domains 1-8. IL.2 AlL soluble species in the diagram have an octahedrally coordinated copper ion bearing water Or hydroxide ligands only: Give the complete formula ad name of the eight species included in the diagram: IL.1 Give the oxidation number of copper in each of the species included in the diagram: The Pourbaix diagram of copper for concentrations in soluble species equal to c=10 moL.L`, is given next page: The species represented in this diagram are (using simplified formula which correspond to the removal of water molecules) HCuOz, CuOz?, CuzOz, Cu?, CuO, Cu", CuzO, Cu.
