sci.galvanic-cell-emf Calculator
Calculates galvanic cell EMF from standard electrode potentials E°cell = E°cathode − E°anode and the Nernst equation for non-standard conditions. Zinc-copper Daniell cell: E° = 1.10 V — Zn²⁺/Zn at −0.76 V, Cu²⁺/Cu at +0.34 V; this was the first practical battery (1836).
