Abstract
A dependence of the potential of silver ion-selective electrode with silver sulfide membrane versus the analytical concentrations of silver ions and thiosulphate is derived theoretically. Equations, valid at a ratio between the molar concentrations of thiosulfate and silver ions at least 20 times and a concentration of thiosulfate from 0.001 to 0.2 mol L-1 are found theoretically and proven experimentally.
