Abstract

The optimal terms for application of molybdenum electrode as an indicatory electrode at the potentiometer measuring were defined. For comparison an industrial platinum electrode was used. Basic electro-analytical properties of electrode in metal salts solutions were found. The ions of metals possess similar electrode functions. The sensitiveness of the investigated electrode is higher than on a platinum electrode. The temperature coefficients of electromotive force on molybdenum electrode were determinated. Thermodynamic characteristics of electrode reaction were calculated.
