Question 1

If an electrolysis plant operates its electrolytic cells at a total current of 1.2 × 106 amp, how long will it take to produce one metric ton (one million grams) of Mg(s) from seawater containing Mg2+? (1 faraday = 96,485 coulombs)

◦ 1.8 h
◦ 1.8 days
◦ 55 min
◦ 0.92 h
◦ 0.46 year

Question 2

In order to determine the identity of a particular lanthanide metal (M), a voltaic cell is constructed at 25°C with the anode consisting of the lanthanide metal as the electrode immersed in a solution of 0.0594 M MCl3, and the cathode consisting of a copper electrode immersed in a 1.00 M Cu(NO3)2 solution. The two half-reactions are as follows:
M(s) → M3+(aq) + 3e–
Cu2+(aq) + 2e–→ Cu(s)
The potential measured across the cell is 2.64 V. What is the identity of the metal?
Reduction Half-Reaction
E° (V)
Cu2+(aq) + 2e–→ Cu(s)
0.34
Ce3+(aq) + 3e–→ Ce(s)
–2.336
Dy3+(aq) + 3e–→ Dy(s)
–2.295
Eu3+(aq) + 3e–→ Eu(s)
–1.991
Gd3+(aq) + 3e–→ Gd(s)
–2.279
Sm3+(aq) + 3e–→ Sm(s)
–2.304
