Consider the following cell: Pt|H₂(g,1 atm) |H⁺(aq,? M) m Ag⁺(aq,1.0 M) |Ag(s)
If the voltage of this cell is 1.04 V at 25^$\circ$C and the standard potential of the Ag⁺/Ag couple is +0.80 V,calculate the hydrogen ion concentration in the anode compartment.

Question

Quizplus · Accepted Answer

The cell potential is given by the Nernst equation: E = E° - (RT/nF)lnQ. The standard cell potential E° is 0.80 V (Ag+/Ag) - 0 V (H+/H2) = 0.80 V. The measured cell potential is 1.04 V. Solving for Q using the Nernst equation and substituting the known values, the hydrogen ion concentration is calculated to be approximately 8.8 * 10^-5 M.
