Practice question
Question
What is the standard cell potential for a galvanic cell where iron is oxidized and silver ions are reduced? (Given: E°Fe²⁺/Fe = -0.44 V , E°Ag⁺/Ag = 0.80 V )
Explanation
Reaction: Fe(s) + 2Ag⁺(aq) → Fe²⁺(aq) + 2Ag(s) . E°cell = E°cathode - E°anode = 0.80 - (-0.44) = 1.24 V .
