1A. A voltage of 2.35 V was measured using a Ag/AgCl reference electrode with saturated KCl. What would this potential be if it were measured using a standard hydrogen electrode?
1B. What would the potential be if it were measured using a saturated calomel electrode?
2. At 25o C for an "ideal" pH electrode, what is the change in voltage between a pH 2.00 solution and a pH 7.00 solution? Place your answer in units of mV.
