Abstract
Inventia se refera la o metoda de analiza a baii de argintare electrochiomica conform careia în scopul determinarii continutului de cianura libera ti de argint într-o singura proba, se efectueaza o titrare cu o solutie de azot de argint, 0,1 n, în prezenta de difenilcarbazona 0,3%, în alcool etilic la primul punct de echivalenta solutia se soloreaza în violet, la al doilea punct de echivalenta se formeaza în precipitat albastru.The invention relates to a method of analyzing the electrochemical silver bath according to which, in order to determine the free cyanide content of silver in a single sample, titration is carried out with a silver nitrate solution, 0.1 n, in the presence of diphenylcarbazone 0.3%, in ethyl alcohol at the first point of equivalence, the solution is solubilized in violet, at the second point of equivalence it is formed in the blue precipitate.
