Homework Answers
1) Al get oxidized
2) Al(s) = Al3+(aq) + 3e-
Anode is the half cell in which oxidation occurs
3) 3Pb2+(aq) + 2Al(s) = 2Al3+(aq) + 3Pb(s)
4) 6 Electrons are exchange in a balanced reaction
5 )E0 cell = E0 el Pb - E 0 el of Al
E0 cell = - 0.126 - - 1.66 = 1.66 - 0.126= 1.534V
Option a
6) option d
Electron do not travel
Ion in salt bridge moves to maintain balance
