Question

Which reaction has been chosen as the 'standard' against which every other reaction is measured?


A. Li+ + e– --> Li
B. F2 + 2e– --> 2F–
C. 2H+ + 2e– --> H2
D. O2 + 4H+ + 4e– ==> 2H2O
E. H2 + 2e– ==> 2H

Answer 1

It's C although you may get some argument from some BECAUSE, technically, the H^/H2 electrode is actually platinized Pt in a 1 M H^+ solution with H2 gas at 1 atm.
