A Voltaic Cell Is Made by Placing an Iron Electrode

question 15

Multiple Choice

A voltaic cell is made by placing an iron electrode in a compartment in which the Fe²⁺ concentration is 2.0 × 10^-5 M and by placing a Pt electrode in the other compartment,in which the H⁺ concentration is 3.4 M and = 1.00 atm.The Fe²⁺/Fe half-cell reduction potential is -0.41 V,and the H⁺/H₂ half-cell reduction potential is 0.00 V.What is the value of E° for this cell,and which electrode is the anode?

• A)0.41 V,Fe
• B)0.90 V,Pt
• C)-0.41 V,Pt
• D)-0.41 V,Fe
• E)0.41 V,Pt
