Standard conditions for galvanic cells

WebbDefinition: Galvanic Cell. It is a type of electrochemical cell where electrons are generated spontaneously through a redox reaction; these electrons pass through an external circuit. Another name for a galvanic cell is a voltaic cell. Galvanic cells convert c h e m i c a l e n e r g y e l e c t r i c a l e n e r g y .

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… WebbIn fact, that is exactly the potential measured under standard conditions if a cell is constructed with the following cell diagram: Co ( s) ∣ Co2 + (aq, 1M) ∥ Cu2 + (aq, 1M) ∣ Cu(s) E° = 0.59V. This cell diagram corresponds to the oxidation of a cobalt anode and the reduction of Cu 2+ in solution at the copper cathode. WebbThe point is that delta G is equal to zero at equilibrium.
