?.6 Draw the two lines corresponding to the redox couples of water on the Pourbaix diagram of copper (E(02/H20)= 1.23 V. Calculate the corresponding solubility product. IL.5 The vertical segment between domains 2 and 3 corresponds to a pH of 7.2. II.4 Determine the slope of the border between domains 1 and 2.

II.3 Identify the species corresponding to each of the domains 1-8. Give the complete formula and name of the eight species included in the diagram. All soluble species in the diagram have an octahedrally coordinated copper ion bearing water or hydroxide ligands only. The species represented in this diagram are (using simplified formula which correspond to the removal of water molecules) HCuo, Cuo, CuzO, Cu', Cuo, Cu, Cu,O, Cu IL.1 Give the oxidation number of copper in each of the species included in the diagram. supplement to study Pourbaix diagrams for the equilibria relevant to bronze. The first is the solubility product of cupric oxide, where we prefer the more recent determination of Nasanen and Tainminen 5 this is misquoted in the Atlas9 as referring I I Cu2 + I Cu(MH3) Cu I I I i I & pH Ht 0 OH- 3795 NH3 6 H30 69 NH4 9. aqueous copper species and chloride ions other thermodynamic variables are. Transcribed image text: Problem II-Pourbaix diagram of copper The Pourbaix diagram of copper for concentrations in soluble species equal to c-10 mol.L is given next page. CONSTRUCTION OF DIAGRAM All copper data have been taken from the Pourbaix tlas7 with two exceptions.
