1.065 g of stainless steel was dissolved in hydrochloric acid (chromium as Cr 3+ ) and diluted to 500.0 ml. A 50.00 ml sample was passed through a Walden reducer, where only iron is reduced (Fe3+ + e-  Fe2+), and titrated with 0.01920 M KMnO4 solution, which consumed 13.72 ml. A 100.0 ml sample was passed through a Jones reducer (Cr3+ + e-  Cr2+ and Fe3+ + e-  Fe2+) into 50.00 ml of a 0.1000 M Fe3+ solution. The resulting solution was titrated with 0.01920 M KMnO4 solution and 36.43 ml was consumed. Calculate the Fe and Cr concentrations of the sample in weight percent.

Consider the formation of gibbsite from dissolved aluminum as depicted below: Al3+ + OH- --> Al(OH)3 (gibbsite) a) balance this reaction (if necessary) b) predict how many mg of Al(OH)3 would be formed if 3 mg of Al3+ are dissolved in 1 l of water and “unlimited” OH- is available (assume this reaction goes completely to the right; there’s no worry about equilibrium dissolved Al3+).
A sample of steel weighing 2.00 g is analyzed for Cr (AW 52.0). The Cr is oxidized into chromate with alkaline permanganate and the excess permanganate is destroyed. A certain volume of 0.120 M FeSO4 is added to the acid solution and the excess is titrated with 0.0220 M KMnO4, requiring 31.0 mL. If the sample contained 0.50 % Cr, what volume (in mL) of FeSO4 was added?
