2 Consider the cell notation below; Al(s) Al³+ (aq,0.150 M) || Fe³+ (aq,0.150 M), Fe²+ (aq,1.50 M) | Pt [EA3+1A= -1.66 V; EFe3+Fe2+ = +0.77 V] (a) Write the balanced overall equation. (b) (c) If salt bridge contains sodium nitrate solution, NaNO,(aq), determine to which compartment (anode or cathode) the nitrate ions, NO, will migrated to. [1] Calculate Ecell. [1] I [2]
(d) (e) Calculate Ecell. [3] I Suggest how the change in [Fe³+] (increase or decrease) would increase the cell potential, Ecell. [1]
