5. In the interpretation of Pourbaix diagrams, corrosion is considered to occur when the concentration of dissolved metal ions attains a minimum concentration of 1.0 x 10-6 M. Suppose that a

0.50-cm² sample of aluminum immersed in 1.0 L of an aqueous solution corrodes at a constant current density of 100 μA/cm². How long will it take to produce a concentration of 1.0 x 10-6 MAI³+?
