Re: Battery type for calibration reference

Anyway, the electric potentials from the reactions are readily
available for calculation -- for example, the standard Cu/Zn combo
yields a predicted (+0.342 - -0.762) = 1.104V of potential difference.

Those potentials are for 25 C temperature, a 1 M concentration of
solutions, and 1 atm pressure of any gasses involved in the battery
chemistry. Deviate from those, and the voltage changes.
