Question 1

A galvanic cell consists of a Al3+/Al half-cell and a standard hydrogen electrode. If the Al3+/Al half-cell standard cell functions as the anode, and the standard cell potential is 1.66 V, what is the standard reduction potential for the Al3+/Al half-cell?
◦ -0.55 V
◦ -1.66 V
◦ +1.66 V
◦ +0.55 V

Question 2

What is the relationship between the standard cell potentials, E°, for the following two galvanic cell reactions?

I.3 Cu2+(aq) + 2 Al(s) → 3 Cu(s) + 2 Al3+(aq)
II.30 Cu2+(aq) + 22 Al(s) → 30 Cu(s) + 22 Al3+(aq)

◦ E°(I) = 10E°(II)
◦ E°(I) = E°(II)
◦ E°(I) = E°(II)
◦ E°(I) = E°(II)10
