A cell consists of a gold wire and a saturated calomel electrode (S.C.E.) in a 0.190 M AuNO3 solution at 25 °C. The gold wire is connected to the positive end of a potentiometer, and the S.C.E. is connected to the negative end of the potentiometer. a.) What is the half‑reaction that occurs at the AuAu electrode? Include physical states. b.) The standard reduction potential for the half‑reaction that occurs at the gold electrode is ?∘=1.69 V. What is the potential of the half-reaction that occurs at the gold electrode under the given conditions? Ignore activities. c.) The reduction potential for the saturated calomel electrode is ?=0.241 V. What is the cell potential?

Question

A cell consists of a gold wire and a saturated calomel electrode (S.C.E.) in a 0.190 M AuNO3 solution at 25 °C. The gold wire is connected to the positive end of a potentiometer, and the S.C.E. is connected to the negative end of the potentiometer.

a.) What is the half‑reaction that occurs at the AuAu electrode? Include physical states.

b.) The standard reduction potential for the half‑reaction that occurs at the gold electrode is ?∘=1.69 V. What is the potential of the half-reaction that occurs at the gold electrode under the given conditions? Ignore activities.

c.) The reduction potential for the saturated calomel electrode is ?=0.241 V. What is the cell potential?
