Ascorbate and Cu ions have the following electrochemical potentials;
Dehydroascorbate + 2H+ + 2e- --> Ascorbate Eo' = +0.08V
Cu2+ + e- --> Cu+ Eo' = 0.159 V
10 mL of a 0.02M solution of ascorbate in a buffered solution at pH 7.0; 25 degrees Celsius is mixed with 10mL of 0.02 M of Cu2+.
Write a balanced chemical equation for the reaction, and figure out the equilibrium concentration of dehydroascorbate, ascorbate, Cu2+, and Cu+.
