Calculate the standard cell potential given the following standard reduction potentials:
Al3++3e−→Al;E∘=−1.66 V
Fe2++2e−→Fe;E∘=−0.440 V
Express your answer to two decimal places and include the appropriate units.
Al3++3e−→Al;E∘=−1.66 V
Fe2++2e−→Fe;E∘=−0.440 V
2Al(s) -------------->2 Al^3+ (aq) + 6e^- E0 = 1.66v
3Fe^2+ (aq) + 6e^- ----------> 3Fe(s) E0 = -0.44v
-------------------------------------------------------------------------------------------------------
2Al(s) + 3Fe^2+ (aq) ----------------> 2Al^3+ (aq) + 3Fe(s) E0cell = 1.22v >>>>answer
