Oxidation potential of Hydrogen gas electrode:
The hydrogen gas electrode is a standard electrode used as a reference electrode for measuring the potential of other electrodes.
Preparation of Hydrogen gas electrode:
- Dip platinum wire in a solution of HCl of pH = 10.
- Pass hydrogen gas around the platinum wire at one atm pressure.
Oxidation potential of the electrode:
- The oxidation potential of the electrode is given by the Nernst equation:
E = E° + (RT/nF) ln ([Ox]/[Red])
where E is the cell potential, E° is the standard cell potential, R is the gas constant, T is the temperature, n is the number of electrons transferred in the reaction, F is the Faraday constant, [Ox] is the concentration of the oxidized form, and [Red] is the concentration of the reduced form.
- Since the hydrogen gas electrode is a standard electrode, its standard potential is known to be 0 V.
- The concentration of hydrogen gas is assumed to be 1 atm, which is equivalent to 1.013 x 10^5 Pa.
- The concentration of hydrogen ions in the HCl solution is given by pH = -log[H+], which is 10^-10 M.
- The reduction half-reaction for the hydrogen gas electrode is:
H+ + e- → 1/2 H2
- Therefore, the oxidation half-reaction is:
1/2 H2 → H+ + e-
- The number of electrons transferred in the reaction is 1.
- Substituting the values into the Nernst equation, we get:
E = 0 V + (8.314 J/K mol) (298 K) / (1 mol) ln (1/10^-10)
E = 0.059 V
- Therefore, the oxidation potential of the hydrogen gas electrode is 0.059 V.
Answer: Option B (0.59 V)
