Academics

Problem- A cell consists of a gold wire and a saturated calomel electrode (S.C.E.) in a 0.140 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.

What is the half-reaction for the Au electrode?

Ignoring activities, if the standard reduction potential for the above reaction is E0 = 1.69 V, what is potential of the gold electrode? (in V)

The reduction potential for the saturated calomel electrode is E = 0.241 V. What is the cell voltage? (in V)
