Question

For the cell shown, the measured cell potential, Ecell, is -0.3671 V at 25 °C. Pt(s) | H2(g, 0.899 atm) | H+(aq, ? M) || Cd2+(aq, 1.00 M) | Cd(s) The balanced reduction half-reactions for the cell, and their respective standard reduction potential values, E°, are 2 H+(aq) + 2 e- ? H2(g) E° = 0.00 V Cd2+(aq) + 2 e- ? Cd(s) E° = -0.403 V Calculate the H+ concentration. [H+] = M

          For the cell shown, the measured cell potential, Ecell, is -0.3671 V at 25 °C.

Pt(s) | H2(g, 0.899 atm) | H+(aq, ? M) || Cd2+(aq, 1.00 M) | Cd(s)

The balanced reduction half-reactions for the cell, and their respective standard reduction potential values, E°, are

2 H+(aq) + 2 e- ? H2(g) E° = 0.00 V
Cd2+(aq) + 2 e- ? Cd(s) E° = -0.403 V

Calculate the H+ concentration.

[H+] = M
