Construct a Pourbaix diagram for aluminum showing the following species: Al (s), Al3+(aq), Al(OH)3 (s), and Al(OH)-4 (aq). The Ksp for Al(OH)3 is 1.0 x 10-33, and:
Al(OH)3 (s) + OH- (aq) (equilibrium arrow) Al(OH)4- (aq) K=40
The y-axis should range from -2.5 to +1.5V, and the x-axis should range from pH 0 to 14. In the range of possible pH and potential values for water, what are the only species likely to be present?
