Condosity

Condosity is a comparative measurement of electrical conductivity of a solution.

The condosity of any given solution is defined as the molar concentration of a sodium chloride (NaCl) solution that has the same specific electrical conductance as the solution under test.^[1][2][3]

By way of example, for a 2 Molar potassium chloride (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,^[4][3][5] or the properties of solutes in the physical environment.^[6] When measuring the properties of bodily fluids such as urine, condosity is expressed in units of millimoles per litre (mM/L).^[7][8]
