Develop the Pourbaix diagram for gold (Au) for 0 5 and 2 2 .

Consider only the following reactions.

Cathodic reactions

A. O2 + 4H+ + 4e 2H2O, E 0 = 1.223 V

B. 2H + + 2e H2, E 0 = 0 V

Anodic reactions

C. Au+ + e Au, E 0 = 1.670 V

D. Au3+ + 3e Au, E 0 = 1.498 V

E. Au(OH)3 + 3H + + 3e Au + 3H2O, E 0 = 1.577 V
