3. Consider the Pourbaix diagram of copper a. Identify the immunity, passivation, and corrosion areas of Cu in the Pourbaix diagram. 1.6 + 1.2 + C 0.8 + Cu(OH),(s) 0.4 + Cu,0(s) Cuo -0.4 + Cu(s) -0.8 + -1.2 8. 12 16 pH b. (T/F). The transformation of Cu2* to Cuz0 is both potential-dependent and pH- dependent. (T/F). The transformation of Cu(OH)2 to Cu02?- is both potential-dependent and pH- dependent. . A/43
