What is conductivity?
Electrolytic conductivity is a measure of the ability of a solution to cany a current. In the 1980`s, international agreement adopted the basic unit of electric conductance as Siemens (S)5 and it is defined as the reciprocal of the resistance in ohms of a 1 cm cube of the liquid at a specified temperature. The units of measurement are the reciprocal of ohm/cm, which was expressed as mho/cm. This was usually expressed in millionths of a mho/cm or simply (.imlio. North American practice historically used |imho units, now renamed microsiemens (jiS/cm).
