Question 4 (10 marks) An alloy is subjected to an accelerated corrosion experiment. By weight, its composition is 57.1%Fe, 16.4%Cr,3.4%V,7.1%Mo,3.7%Re, and 12.3%Ni. It is placed in a corrosion cell with a volume of 500 L. The resulting electrolyte was analyzed by several measurements and the following data was obtained. a. What is the average concentration of each element b. What is the total mass of each element present in the corrosion cell c. Does the alloy corrode stoichiometrically? d. From the Pourbaix diagrams for the above metals, what are the possible stable phases for each in the water stability region, and at a pH of 4 and at a pH of 10
