Why Are Graphite Electrodes Used in Electrolysis M

The main reason that graphite electrodes are used in electrolysis is that graphite is an excellent conductor The structure of graphite is such that it has a large number of electrons floating freely between the different layers of atoms graphite bonds are formed of only three out of the four electron shells of the carbon atom leaving the fourth electron to move freely
