Mass of the electrode

Postby Hiseo Lee 2J » Fri Feb 12, 2016 3:12 pm

How come the mass of the electrode does not affect the amount of Voltage it could potentially provide?

The main thing is that the metal electrode itself represents a solid species, and cell potential only changes when a reaction is deviant from equilibrium. Since Q depends on only aqueous species, increasing the concentration of the solid species won't change Q, meaning that the reaction would remain at equilibrium as long as the concentrations of the aqueous species are unchanged.
