Cell EMF Calculator – Electromotive Force of a Cell
Calculate the standard cell potential ($E^\circ_{\text{cell}}$)
Formula: $E^\circ_{\text{cell}} = E^\circ_{\text{cathode}} - E^\circ_{\text{anode}}$ (using standard reduction potentials). A positive cell potential indicates a spontaneous galvanic cell reaction.

Calculation Results
⚠️ Standard cell potentials ($E^\circ$) are strictly valid only under standard conditions (25°C, 1 atm pressure, and 1 M concentration for solutions). For non-standard conditions, the Nernst equation must be applied to determine actual cell EMF.
