Purpose Use a standardized potassium permanganate solution to analyze an unknown iron solution by using redox titration. Theory Reduction-oxidation titration is an analytical method based on electrons transferring between an oxidizing agent and a reducing agent in solutions. Chemical analysis can be built on Redox titration if four criteria are met: a) The reaction is completed in a thermodynamically spontaneous condition. b) The reaction is fast enough to give an operational result instantly

diluted serum samples were centrifuged at 2‚000×g for 10 min and 10‚000×g for 30 min at 4 °C to remove dead cells and cell debris. The supernatant was transferred into Ultra-ClearTM tubes (Beckman Coulter‚ Indianapolis‚ IN) and centrifuged at 100‚000×g using a Beckman Optima XL-70 Ultracentrifuge for 70 min at 4 °C. The supernatant was removed with a pipette and 2 mm of supernatant remained above the pellet. After one cycle of ultracentrifugation‚ it was not possible to remove all of the serum supernatant
