Cadmium chloride, hydrate Use and Manufacturing
The sponge cadmium method heats and melts sponge cadmium, pours cold water to make cadmium flowers, and then reacts with hydrochloric acid to form a cadmium chloride solution. Potassium permanganate is added to remove iron and other impurities in the solution. After clarification, the clear solution is sent to evaporation Concentrated, cooled and crystallized, and centrifuged to produce cadmium chloride. Its Cd 10 2HCl→CdCl2+H2
It is used for standard solutions.
