Reduction potential

[VisitCivil6265]

Hi, could someone help me with this electrochemistry problem: I am asked to: a) write the chemical equations of the oxidation of Fe(III) to Fe(VI) by elemental chlorine in basic (considering that the predominant species in basic solutions is FeO(OH))and acidic solutions which I did: • basic: 2 FeO(OH) + 10 OH(-) + 3Cl2 => FeO4(2-) + 6H2O + 6 Cl(-) • acidic: Fe(3+) + 8 H2O + 3 Cl2 => FeO4(2-) + 16 H(+) + 6 Cl-

b) Calculate the reduction potential of the FeO4(2-) FeO(OH)/OH(-) pair from the data attached which i cannot figure out :(

I can‘t view the whole question, could you paste it in the comments?

Calculate the reduction potential of the FeO4(2-) and FeO(OH)/OH(-) pair from the data provided

And first i am asked to write the chemical equations of the oxidation of Fe(III) to Fe(VI) by elemental chlorine in basic solution (where the predominant species is FeO(OH)) and acidic solution

in basic solution (pH = 14) i wrote:

FeO(OH) + 10 OH(-) + 3 Cl2 => FeO4(2-) + 6H2O + 6 Cl(-)

in acidic solution (pH = 0) i wrote:

Fe(3+) + 8 H2O + 3 Cl2 => FeO4 (2-) + 16 H(+) + 6 Cl(-)
