Data analysis is an essential tenet of analytical chemistry, extending the possible of obtaining information from the measurement of chemical phenomena. Conductivity methods have grown considerably over recent years but their wide use is hindered because some still consider them too complicated. The purpose of this article is to describe a conductivity sensitivity method more simply from the point of view of an analytical chemist, by using mathematical linear and quadratic extrapolations. This conductivity sensitivity method defines sensitivity parameters for determining reactant or product concentrations based on measuring strong and weak electrolytes conductivities. The sensitivity parameters are constant throughout this specific reaction. Concentrations of strong electrolytes can be determined by linear extrapolation, whilst concentrations of weak electrolytes can be determined by quadratic mathematical extrapolation. This method proposes a continuous determination of real reactant or product concentrations.
