Question 1

A galvanic cell consists of a Zn2+/Zn half-cell and a standard hydrogen electrode. If the Zn2+/Zn half-cell standard cell functions as the anode, and the standard cell potential is 0.76 V, what is the standard reduction potential for the Zn2+/Zn half-cell?
◦ -0.38 V
◦ +0.76 V
◦ +0.38 V
◦ -0.76 V

Question 2

A galvanic cell consists of one half-cell that contains Ag(s) and Ag+(aq), and one half-cell that contains Cu(s) and Cu2+(aq). What species are produced at the electrodes under standard conditions?

Ag+(aq) + e- → Ag(s)E° = +0.80 V
Cu2+(aq) + 2 e- → Cu(s)E° = +0.34 V

◦ Cu2+(aq) is formed at the cathode, and Cu(s) is formed at the anode.
◦ Ag(aq) is formed at the cathode, and Cu(s) is formed at the anode.
◦ Cu(s) is formed at the cathode, and Ag+(aq) is formed at the anode.
◦ Ag(s) is formed at the cathode, and Cu2+(aq) is formed at the anode.
