Question

A voltaic cell is being constructed from an Al/A|^ 3+ electrode and a Sn/Sn^ 2+ electrodeWhen constructed properly and the circuit is closed, the tin electrode is observed to gain mass and the overall cell potential to be 1.52V. 

Which of the following chemical reactions takes place at the cathode?
Al3+(aq) + 3e- → Al(s)
Sn(s) → Sn2+(aq) + 2e- 
Sn2+(aq) + 2e- → Sn(s)
Al(s) → Al3+(aq) + 3e- 

Based on the overall reaction taking place across the voltaic cell, how many moles of electrons are involved? 

When electrons are flowing in the cell, which electrode gains mass?
True or false:  If an aluminum electrode is set to be part of a voltaic cell that also involves a standard hydrogen electrode (SHE), the aluminum electrode would be the anode.
