In electrochemistry, specific conductance is defined as (1000/N)* k, where N is the normality of the salt solution and k is the specific conductance. Current is carried by both anions and cations to a different degree. Thus, the equivalence of a salt is the sum of the ionic conductances of the cation and anion.

Electrolysis

Electrolysis is defined as the process of breaking down ionic compounds into their constituent elements by passing a direct electric current through the compound in a fluid state. The cathode reduces cations, while the anode oxidizes anions. An electrolyte, electrodes, and some form of external power source are the main components required for conducting electrolysis. A partition, such as an ion-exchange membrane or a salt bridge, may also be used, but this is optional. These are primarily used to prevent the products from diffusing near the opposing electrode.
