(KCl) solution, the condosity would be expected to be somewhat greater than 2.0. This is because potassium is a better conductor than sodium.

Applications

The measurement is sometimes used in biological systems to provide an assessment of the properties of bodily or cellular liquids, or the properties of solutes in the physical environment. When measuring the properties of bodily fluids such as urine, condosity is expressed in units of millimoles per litre (mM/L).
