Nernst Equation Cell Potential Calculator

Compute cell potential at nonstandard concentrations using standard potential, electron count, and reaction quotient.

Standard E0 (V)

Electrons n

Reaction quotient Q

Core Formula

E = E0 - (0.05916/n) log10(Q) at 25C

Use this for planning estimates and sanity checks.
