The redox reaction of peroxydisulfate with iodide has been used for many years as part of the iodide clock reaction which introduces students to kinetics. if e not cell equals 1.587v and e not redox of the anode half cell is 0.536v, what is e not redox of the cathode half cell? . s2o82-(aq) + 2h+ +2i-(aq) yields 2hso4-(aq) + i2 (aq). a. -1.051v. b. 1.051v. c. -2.123v. d. 2.123v. e. none of these choices is correct
