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 0.33M. This half-cell is connected to a standard hydrogen electrode (SHE) half cell. The measured potential for this cell is 0.453V. What is the experimental value of the solubility product constant for silver oxalate?
