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 solution that has the same specific electrical conductance as the solution under test.
By way of example, for a 2 Molar potassium chloride solution, the condosity would be expected to be somewhat greater than 2.0. This is because potassium is a better conductor than sodium.
