Question 1
Consider the galvanic cell,
Which one of the following changes to the cell would cause the cell potential to increase (i.e., become more positive)?◦ increase the mass of Zn(s)
◦ decrease the mass of Zn(s)
◦ increase the Zn2+ concentration
◦ increase the Pb2+ concentration
Question 2
Based on the following information,| Cl2(g) + 2 e- → 2Cl-(aq) | E° = +1.36 V |
| Mg2+(aq) + 2 e- → 2Mg(s) | E° = -2.37 V |
which of the following chemical species is the strongest reducing agent?
◦ Cl2(g)
◦ Mg2+(aq)
◦ Mg(s)
◦ Cl-(aq)
