Which is the oxidizing agent in the reaction below. Cr2O72- + 6S2O32- +14H+ > 2Cr3+ + 3S4O62- +7H20 A. Cr3+ B. S4O62- C. Cr2O62- D. S2O32- E. H+ I believe it's D or is it C not 100% sure please help. THANKS
Which is reduced in the following reaction: Cr2O72-+6S2O32-+14H+>2Cr3+ + 3S4O62- + 7H20 A. H+ B. Cr6+ C. S4O62- D. S2+ E. O2- I come out with Cr2O72 but that's not an answer so my next one is B. Cr6+ am I correct?
