For the cell shown, the measured cell potential, Ecell is -0.3719 V at 25. Pt(s)|H(g, 0.865 atm)|

For the cell shown, the measured cell potential, Ecell is -0.3719 V at 25℃.

Pt(s)|H₂(g, 0.865 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)+2e^- ⟶ H₂(g)   E⁰=0.00 V

Cd²⁺(aq)+2e^- ⟶ Cd(s)   E⁰=-0.403 V

Calculate the H⁺concentration.
