Four voltaic cells are set up. In each, one half-cell contains a standard hydrogen electrode (SHE). The second half-cell is one of the following. 2+ Fe (aq, 1.0 M) | Fe(s) 4+ Zr" (aq, 1.0 M) | Zr(s) (ад, 1.0 M) | Нg() Hg2 Ca" (aq, 1.0 M) | Ca(s) 2+ 2+ (a) In which of the voltaic cells does the hydrogen electrode serve as the cathode? 2+ SHE & Fe (aq, 1.0 M) | Fe(s) 4+ SHE & Zr" (aq, 1.0 M) | Zr(s) 2+ SHE & Hg," (aq, 1.0 M) | Hg(1) SHE & Ca" (aq, 1.0 M) | Ca(s) 2+ (b) Which voltaic cell produces the highest voltage? Which produces the lowest voltage? The highest voltage will be produced by combining the SHE and the half-cell. The lowest voltage will be produced by combining the SHE and the half-cell.
