If the half-reaction: fe3+ + e- = fe2+ were chosen as the standard reduction potential table reference instead of: 2h+ + 2e- = h2, what would the eo value for zn2+ reduction be?

for system would be -1.53 V

Explanation:

Determination of standard reduction potential of any system is done by placing the system in cathode and a reference half cell in anode and then evaluate the cell potential. The cell potential is the standard reduction potential of the system.

So

As is equal to 0 therefore cell potential is equal to reduction potential of any system by taking hydrogen electrode as a reference.

equal to -0.76 V with respect to hydrogen

equal to 0.77 V with respect to hydrogen

Therefore standard reduction potential of system when system is taken as reference is-

                          = -0.76 V - 0.77 V

                          = -1.53 V
