Using the data from the Appendices of your textbook, (i don\'t have these values) calculate the standard cell potential (emf, E^o_cell) that employs the following reaction.

2Al(s) + 3I₂(s) → 2Al³⁺(aq ) + 6I^-(aq)

_______V

In the above reaction, the Al(s) electrode is the anode or cathode?

The electrode in the beaker containing I₂(s) and I ^-(aq) is the anode or cathode?

Which of the following are correct?

A. the cathode is negative

B. the cathode is positive

C.The anode is negative

D. Electrons flow from cathode to anode

E.The anode is positive

F. electrons flow from anode to cathode.

Solution

Al electrode is anode. Following are correct: cathode is negative, anode is positive and electros flow from cathode to anode.
