Consider a titration of Fe²⁺ by Ce⁓⁺ in 0.5f Hā‚‚SOā‚„ (f = fugacity) in a Galvanic cell with an inert Pt working electrode at 298 K. Refer to the Fe²⁺/Fe³⁺ and Ce⁓⁺/Ce³⁺ pairs on the Electrochemical Series handout on Canvas (Week 4), paying attention to 0.5f Hā‚‚SOā‚„.

Before Ce⁓⁺ is added, the initial iron ion solution contains 1.00 mM Fe²⁺(aq.) and 1E-10 mM Fe³⁺(aq.). What is the initial cell potential (Ecell)?
