Question 1
In a galvanic cell, oxidation occurs at the:
◦ anode
◦ cathode
◦ salt bridge
◦ electrolyte
◦ in cathodic space
Question 2
In a zinc-lead cell the reaction is:
Pb
2+(aq) + Zn(s) → Pb(s) + Zn
2+(aq)
E° = 0.637 V
Which of the following statements about this cell is FALSE?
◦ The zinc electrode is the cathode.
◦ The reaction will go in the direction indicated.
◦ The shorthand notation is Zn(s)

Zn
2+(aq)

Pb
2+(aq)

Pb(s).
◦ The actual cell voltage is less than +0.637 volts because of concentration polarization and possible other factors.
◦ The lead electrode is positively charged.
