However, E naught is measured at standard conditions, and under standard conditions, both sides will have the same concentration (1 M of solution) of the same species at 1 atm. Galvanic cells are extensions of spontaneous redox reactions, but have been merely designed to harness the energy produced from said reaction. For example, when one immerses a strip of zinc metal (Zn) in an aqueous solution of copper sulfate (CuSO4), dark-colored solid deposits will collect on the surface of the zinc metal and the blue color characteristic of the Cu ion disappears fro…
