The conductivity of an aqueous solution is the measure of its ability to carry an electrical current by
means of ionic motion.
The conductivity invariably increases as the temperature rises.
It is affected by the type and number of ions in the solution and by the viscosity of the solution itself.
Both parameters are temperature dependent. The dependency of conductivity on temperature is
expressed as a relative change per Celsius degree at a particular temperature, commonly as percent
per

°

C (%/
