MCAT Question of the Day


  • Q:

    A galvanic cell is set-up between an Ag-AgCl electrode and standard hydrogen electrode. Some standard reduction potentials are provided. What is the potential across in this electrochemical cell?

    2H+ + 2e- → H2 (E° = 0.00 V)
    2H2O + 2e- → H2 + 2OH- (E° = -0.83 V)
    Ag+ + e- → Ag (E° = 0.80 V)
    AgCl + e- → Ag + Cl- (E° = 0.22 V)


     

    A

    0.44 V

    B

    1.63 V

    C

    0.22 V

    D

    0.00 V
