Question:
An experimental cell is set up such that one half cell contains a solid silver electrode dipping into a saturated solution of silver oxalate. The oxalate ion comes from added sodium oxalate so that equilibrium concentration of oxalate ions is 0.50 M. This half-cell is connected to a standard hydrogen electrode (SHE) half-cell. The measured potential for this cell is 0.476 V at 25 C. What is the experimental value of the solubility product constant for silver oxalate?
Voltaic Cell:
A voltaic cell is an electrochemical cell that derives electrical energy from a spontaneous oxidation-reduction (redox) reaction occurring inside the cell. The overall redox reaction is arranged around anode and cathode compartments, where the oxidation and reduction half reactions occur respectively. Each of these processes have half-cell potential values, with the two electrodes in the cell selected such that the overall cell potential is a positive value at the given conditions.
