reduktionpotentialer
Reduktionpotentialer are a measure of the tendency of a chemical species to gain electrons, i.e., to be reduced, in redox reactions. They are most commonly expressed as standard reduction potentials, E°, relative to the standard hydrogen electrode (SHE) at 25°C in aqueous solution where activities are unity.
Standard reduction potentials are defined for redox couples A^n+/A^(n-1) e− and are determined under standard conditions
The Nernst equation relates E to the actual conditions: E = E° − (RT/nF) ln Q, where Q
Common examples at standard conditions include the hydrogen couple (2H+ + 2e− → H2, E° = 0 V), Fe3+/Fe2+
Applications span electrochemistry, battery design, corrosion science, electrolysis, biosensors, and environmental redox processes. In practice, accurate
