The other half-cell contains theĬathode and an electrolyte containing the same metal cations. If a box is not needed, leave it blank.) The. Use the pull-down boxes to specify states such as ( aq) or ( s ). The half-cell compartments are connected by a salt bridge.

One half-cell contains the anode andĪn electrolyte containing the same metal cations. Coupling this low-potential aldehyde oxidation reaction with a cathodic HER enables a bipolar hydrogen production system, with H 2 production at both the cathode and anode, which is fundamentally. A voltaic cell is constructed in which the anode is a Fe Fe2+ half cell and the cathode is a Cu Cu2+ half cell. Its potential for doing work must therefore be zero. If there is no longer a net flow of electrons, the cell can no longer do electrical work. Galvanic cells are actually made up of two half-cells. When the reaction is at equilibrium, there is no net change in the amount of zinc metal or copper ions in the system, so no electrons flow from the anode to the cathode.

Compare the sum of the Cu-Zn and Zn-Mg cell potentials with the Cu-Mg cell potential. What is the oxidizing agent in the Zn-Mg cell 3.
