The copper coulometer is a one of the common application of the Copper-copper(II) Sulfate Electrode . Such a Coulometer consists of two identical copper eletrodes immersed into the slightly acidic PH-buffered solution of the Copper(II) Sulfate . Passing of the Current through the element leads to the anodic Dissolution of the metal on Anode and simultaneous Deposition of the Copper -ions on the Cathode . These reactions have 100% efficiency over a wide range of the current densities. Amount of the Quantity Of Electricity passed through the cell can be easily calculated by mass changes of any of the electrodes:
where Q is the quantity of electricity (coulombs); is the mass transported (gm); 63.546 is the Atomic Weight of copper, the factor 2 is due to the transport of Divalent ions, and F is the Faraday Constant (96485.3383). |
