a 1.065g sample of stainless steel was dissolved in HCL(this treatment converts Cr present to Cr3+) and diluted to 500mL in a volumetric flask. One 50mL aliquot was passed through a Walden reductor and then titrated with 13.72mL of 0.01920M KMnO4. A 100mL aliquot was passed through a Jones reduction into 50mL of 0.1 M Fe3+. titration of the resulting solution required 36.43 mL of KMnO4 solution.Calculate the percentage of Fe and Cr in the alloy.
