sci.electrochemical-cell-voltage Calculator
Calculates the equilibrium cell voltage of an electrochemical cell from half-reaction standard potentials and the Nernst equation. The standard hydrogen evolution reaction has E° = 0 V vs SHE — water electrolysis requires a minimum of 1.23 V (thermodynamic) plus overpotential losses.
Inputs
E Reduction Cathode
Reference formula or conversion factor shown for context.
E Reduction Anode
Reference formula or conversion factor shown for context.
Concentration Cathode
Amount of solute per unit volume. Higher concentration = more solute dissolved.
Concentration Anode
Amount of solute per unit volume. Higher concentration = more solute dissolved.
Results
standard cell voltage (V)
Electric potential difference between the two terminals (V). In AC systems, quoted as RMS — 230 V mains has a peak of ~325 V.
Nernst voltage at concentrations
Electric potential difference between the two terminals (V). In AC systems, quoted as RMS — 230 V mains has a peak of ~325 V.
