In Lab: In one beaker: 10 mL of .005 M KMnO4 + 8 mL 1M NaOH + 15 mL .01M Na2SO3 In another bkr: 10 mL of .005 M KMnO4 + 15 mL .01 M Na2SO3 In another: 10 mL .005 M KMnO4 + 10 mL 1M H2SO4 + 25 mL .01 M Na2SO3 Write/balance 3 redox reactions (half-reactions) in neutral, acidic and basic medium. Use S2O32- instead of HSO3- as reducing agent, assuming SO42- as product derived from S2O32- for all reactions (using H+ or H20 for acidic & OH- or H2O for basic)
