An attempt is made in the published article to use a hypothetical “sulfide and steel half-cell” for the rapid determination of the concentration of hydrated sulfide-ion. The potential of such an half-cell was defined as an electromotive force of galvanic cell (EMF or voltage, V) in combination with a silver chloride half-cell (comparisons). A linear relationship was obtained between the sulfide content and the EMF of the above element. Some results on the selectivity of the half-cell under consideration were presented. The temperature dependence of the potential expressed through EMF of the latter is obtained.
