Consider an electrochemical cell with the following cell notation:
Fe(s)| Fe²+ (aq) (from saturated FeCO3) || Fe²+ (aq) (0.150 M) | Fe(s)
Given: Ksp of FeCO3 is 3.5 x 10-11
Eºred Fe²+/Fe = -0.44V
Which of the following is the expected oxidation half-reaction based on the given cell notation?
O FeCO3(s) Fe²+ (aq) + CO3²- (aq)
O Fe²+ (aq) + CO3²- (aq) =1
FeCO3(s)
O Fe2+
*(aq) + 2 e¯ = Fe(s)
O Fe(s) Fe²+
*(aq) + 2 e-
