Question

My lab Data

List the electrochemical series you developed from this lab based on the experimental values you obtained. Compare this to a published electrochemical series list, like the one in your eScience lab manual. Is yours different? If so, in what way is it different?

Explanation / Answer

Based on the electrochemical series, the cell reactions we developed here are,

with Al as the anode,

2Al(s) + 3Zn2+(aq) ---> 2Al3+(aq) + 3Zn(s)

2Al(s) + 3Fe2+(aq) ---> 2Al3+(aq) + 3Fe(s)

2Al(s) + 3Sn2+(aq) ---> 2Al3+(aq) + 3Sn(s)

with Zn as the anode,

Zn(s) + Fe2+(aq) ---> Zn2+(aq) + Fe(s)

Zn(s) + Sn2+(aq) ---> Zn2+(aq) + Sn(s)

with Fe as the anode,

Fe(s) + Sn2+(aq) ---> Fe2+(aq) + Sn(s)
