Assume that you want to construct a voltaic cell that uses the following half reactions:
A2+(aq)+2e−→A(s)E∘red=−0.14VB2+(aq) +2e−→B(s)E∘red=−1.18V
You begin with the incomplete cell pictured below, in which the electrodes are immersed in water.
What additions must you make to the cell for it to generate a standard emf?
Check all that apply.
A. We should add enough salt containing A2+ into the glass containing the electrode A(s) to produce a 1 M A2+ solution..
B. We should add the salt brige.
C. We should add enough salt containing B2+ into the glass containing the electrode B(s) to produce a 1 M B2+ solution.
D. We should apply the initial emf to the electrodes.
E. We should add enough salt containing A2+ into the glass containing the electrode B(s) to produce a 1 M A2+ solution..
F. We should add enough salt containing B2+ into the glass containing the electrode A(s) to produce a 1 M B2+ solution.
G. Which electrode functions as the cathode?
electrode A
electrode B
Which direction do electrons move through the external circuit?
from A to B
from B to A
What voltage will the cell generate under standard conditions?
