Based on the principle of electrochemistry, a relationship between conductivity of a binary solution and equivalent concentrations of the components was derived, which elucidates the standard curve of conductivity. The concentration in a binary system can be determined from those of their corresponding pure component, therefore, it allows us to evaluate the concentration of one component easily and fast with a predetermination of concentration of the other. This method is expected to become a useful supplement to chemical analysis or instrumentation.
