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 with increasing temperature.
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 ºC.
The following table lists the temperature dependence of the HANNA
calibration buffers.
