Electrochemical Cells

• A graphite rod can be used as the electrode in such half-cells
• These voltages can be used to arrange the elements into an electrochemical series
• The metals are attached through bikes, elections down through the wires and less how through the salt bridge
• Electricity can be produced in cells where at least one of the half-cells does not contain a metal that can donate or receive atoms/ions
• An electrochemical bell can be produced where two metals are placed in a solution of their own ions and linked with a salt bridge to complete the circuit
• Other half-cell pairs produce different voltages
• The further apart the elements are in the electrochemical series, the greater the voltage produced when they are used to make an electrochemical cell
