Which of the following are true statements about the above voltaric cell and the resulting cell chemical reaction ?
a) The zinc electrode is the cathode
b) Zinc will be consumed before copper
c) Electrons flow from the copper electrode to the zinc electrode
d) The half reaction for the anode is Cu2+(aq) + 2e− → Cu(s)
e) The species SO42− does not take part in the cell reaction
The Attempt at a Solution
i know a is false because zinc is the anode.
i know c is false because electrons flow from the zinc to the copper & ions flow from the copper to the zinc
i know d is false because the half reaction is the Oxidation at the anode Zn(s) --> Zn2+(aq) + 2e-
i believe e is true
Reduction at the cathode
2H3O+(aq) + 2e --> H2(g) + 2H2O(l)
any other help with this?
