Electrode and Cell Potentials Flashcards
- Describe and relate the definitions of electrode and cell potentials. - Interpret electrode potentials in terms of relative oxidant and reductant strengths. - Calculate cell potentials and predict redox spontaneity using standard electrode potentials.
Cell Potentials
The voltage produced by Galvanic cell, showing how much electrical energy the redox reaction generates.
Standard Cell Potentials
The cell potential measured when everything is at standard conditions (1 M for solutions, 1 arm for gases, 25 degrees C).
Standard Hydrogen Electrode (SHE)
A reference electrode used to measure other electrode’s potentials. It has a potential of 0.00 V and involves hydrogen gas and platinum electrode.
Electrode Potential
The voltage of a single electrode in a half-cell, showing its tendency to gain or lose electrons.
Standard Electrode Potential
The electrode potential measured under standard conditions, compared to the standard hydrogen electrode.
