摘要：

This article gives a critical review of the current data on the specific conductivity of aqueous potassium hydroxide (KOH) solutions. Empirical correlations relating concentration to density were developed to compare specific conductivity data given in weight percentage KOH and molarity of KOH. Available data on specific conductivity is related with respect to one another and compared to experimental data. Based on these comparisons, specific sets of reported data were used to develop an equation relating specific conductivity of aqueous KOH to temperature and concentration. This empirical correlation was developed over a molarity range of 0-12 at temperatures of 0-100 degrees C. The correlation has been compared with that proposed by See and White and shows greater accuracy over the concentration range modeled. (c) 2006 International Association for Hydrogen Energy.
