How Do Electrons Flow in a Galvanic Cell

Under this convention the emf of the cell is positive and is given by the potential of the half-cell on the right hand side minus the potential of. A galvanic cell is generally represented by putting a vertical line between metal and electrolyte solution and putting a double vertical line between the two electrolytes connected by a salt bridge.

A galvanic cell whose electrodes are zinc and copper submerged in zinc sulfate and copper sulfate respectively is known as a Daniell cell.

. Diffusion is driven by a gradient in Gibbs free energy or chemical potentialIt is possible to diffuse uphill from a region of lower concentration to a region of higher concentration like in spinodal decomposition. This flow of electrons is an electric current that can be used to do work such as turn a motor or power a light. Bertrand University of Missouri-Rolla Background.
