A standard galvanic cell is constructed in which
a H+ | H2 half
cell acts as the cathode. Which of the
following statements are correct?
Hint: Refer to a table of standard reduction potentials.
(Choose all that apply.)
Hg2+|Hg could be the other standard half cell.
In the external circuit, electrons flow from the other
compartment to the
H+|H2 compartment.
The cathode reaction is H2 ->
2H+ + 2e-.
Mn2+|Mn could be the other standard half cell.
As the cell runs, anions will migrate from the other compartment
to the H+|H2 compartment.
