Conductometric determination of ethanol concentration

Abstract

Conductivity of the dyes, methylene blue, crystal violet and a mixture of both dyes in aqueous solutions increased with concentration giving a linear relationship in each case.  The conductivity of various ethanol concentrations in aqueous solution with dyes and a combination of the dyes generally decreased with ethanol concentration. But the reciprocal of conductivity increased with ethanol concentration, and in a particular case where a mixture of crystal violet and methelene blue was used, the reciprocal of conductivity of the ethanol concentrations was linear.
