The shorthand notation for the galvanic cell reaction Fe³⁺(aq)+ 2 I^-(aq)→ Fe²⁺(aq)+ I₂(s)requires an inert electrode on A)both sides of the salt bridge. B)neither side of the salt bridge. C)only on the left side of the salt bridge. D)only on the right side of the salt bridge.

Question

Quizplus · Accepted Answer

The inert electrode is required on the side of the cell where the oxidation reaction occurs. In this case, the oxidation reaction is Fe²⁺(aq)→ Fe³⁺(aq)+ e^-, which occurs on the left side of the salt bridge. Therefore, the inert electrode is required on the left side of the salt bridge.
