Abstrakt: The electrical conductivity of the aqueous solutions of ammonium perrhenate is studied in the reagent concentration range 0.01–0.2 mol/L based on metal at aqueous solution temperatures of 20–50°C. The electrical conductivity is found to increase linearly with the electrolyte temperature and nonlinearly with the reagent concentration. The temperature coefficients and the activation energy of the electrical conductivity are calculated in the given concentration and temperature ranges. The activation energy of the electrical conductivity is shown to decrease as the solution temperature increases and to slightly depend on the ammonium perrhenate concentration in the solution.
