What is electrode potential?
Electrode potential is the ability of an electrode to drive an electrochemical reaction, measured in volts.
What is the standard electrode potential (E°)?
The standard electrode potential (E°) is the electrode potential measured under standard conditions, specifically at 25°C, 1 atm pressure, and 1 M concentration for all solutes.
What is a positive electrode potential?
A positive electrode potential indicates that the electrode is effective at reducing species in an electrochemical reaction, favoring reduction.
What does a negative electrode potential indicate?
A negative electrode potential indicates that the electrode is less favorable for reduction and indicates oxidation is more likely.
How are standard electrode potentials used in calculations?
Standard electrode potentials are used to calculate the cell potential using the Nernst equation and to predict the direction of redox reactions.
