General Chemistry I (CHEM 101) Electrochemistry, Redox, Galvanic Cells, and Nernst Equation Exam Review
University of Florida
General Chemistry I (CHEM 101) | Exam Review

Overview
An exam review for electrochemistry that helps students balance redox, assign anode/cathode correctly, and apply the Nernst equation without sign mistakes.

Key topics
•oxidation reduction and balancing methods
•galvanic vs electrolytic cells and cell notation
•E cell and delta G relationships
•Nernst equation and reaction quotient Q

Suggested study tasks
•label anode cathode and electron flow for four cells
•write two full cell notations from descriptions
•compute E cell under nonstandard conditions using Nernst

Common pitfalls
•multiplying E degrees by coefficients
•reversing anode and cathode signs
•using Q incorrectly or forgetting log base 10 factor
