摘要：
The specific electrical conductivity (EC) of the KOH-H2O system was analyzed in the range 0-100 degrees C. The maximal EC of KOH solutions for a given temperature and the concentration corresponding to the maximal specific EC were used as generalizing parameters. The values of normalized EC (the ratio of the EC to its maximal value for a given temperature) fall on one curve for temperatures over a range of 0-100 degrees C and concentrations over a range of 0.01-12 mol/L if the normalized concentration (the ratio of the solution concentration to the concentration corresponding to the maximal specific EC) is used as the argument. The normalized EC values for NaOH-H2O and LiOH-H2O systems fall on the same curve. Analytical expressions fitting normalized EC as a function of concentration are given.
