Web14 Jan 2016 · Chapter 2 of the Pourbaix Atlas [ 4] presented the method of calculation and the procedure of the construction of an Eh-pH diagram. The process was relatively simple since only one component was considered. Garrels and Christ [ 2] dedicated a full chapter to the Eh-pH diagrams. Web(a) Al has a recycling cost is 5% of the original production cost, the lowest of all engineering metals. Explain the main factors contributing to its recyclability. (b) Groundwater contains about 1 ppm [Al 3 +] and 0.1 ppm [AlO 2 − ] in molar concentration. Using the Al Pourbaix diagram below, identify the pH range(s) within which Al is
