Question:
A chemist measures the potential of an electrochemical cell
vs. the saturated calomel electrode to be +0.5V. Then, the chemist
switches the reference electrode to the silver-silver chloride
electrode.
What should the voltage read?

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.
