Abstract

The electrical conductivity (EC) of ammonium heptamolybdate solutions in the concentration range 0.01–0.6 mol/L (based on Mo(IV)) is studied as a function of the reagent content in the solution and its temperature. The EC of the solution is shown to linearly increase with temperature. At a constant temperature of the solution, its EC increases nonlinearly as the ammonium heptamolybdate concentration increases. The linearization of the obtained temperature dependences of the EC makes it possible to calculate the temperature coefficients of the EC in the reagent concentration range under study and to determine the activation energy of the EC in the temperature range under study.
