Electron Economics

Electrons want to get from place to place

Electromotive Force, EMF, volts

? AL + ? H₂O = ? H₂ + Al(OH)₃

Anode and Cathode

Caustic Soda on aluminum foil--anodic and cathodic sites

Caustic Soda on aluminum anode connected to graphite cathode

Caustic Soda on aluminum anode disconnected from graphite cathode--collecting the “toll”

Current: depends on the EMF, the area of the electrodes, and the size of the wire

Power: volts times amps = watts
