A chemist designs a galvanic cell that uses these two half-reactions: half-reaction standard reduction potential
Zn2+(aq) + 2e- → Zn(s) E0red = -0.763
2IO3-(aq) + 12H+(aq) + 10e- →I2(s) + 6H2O(I) E0red = +1.195
a. Write a balanced equation for the half-reaction that happens at the cathode.
b. Write a balanced equation for the half-reaction that happens at the anode.
c. Write a balanced equation for the overall reaction that powers the cell.
Do you have enough information to calculate the cell voltage under standard conditions?
