Question
In a voltaic cell, one compartment/electrode is a Ag*(0.600 M) | Ag(s) half-cell, the other is a
standard hydrogen electrode (saturated hydrogen gas on Pt metal) immersed in a 0.040 M HCI
solution.
a.
Write the line notation for the cell, including all concentrations, partial pressures and
states. Write the two half-reactions (clearly indicate if it is the anode or cathode) and the overall
reaction of this voltaic cell.
b.
Calculate Eo
cell -
C.
Calculate Ecell at 25 °C.
d.
Calculate Ecell at 25 °C if the hydrogen electrode is immersed in a buffer solution
containing 0.064 M acetic acid, CH3COOH (MM = 60.05 g-mol-1) and 0.376 M sodium acetate,
NaCH3COO (MM = 82.03 g-mol-1). Use pka (CH3COOH) = 4.8.
