English description（英文原文，共 1217 字符）
Product Name:Cadmium chloride hemipentahydrate
English Name:Cadmium chloride hemipentahydrate
CAS No.:7790-78-5
Aliases:Cadmium chloride hydrate, Cadmium dichloride hemipentahydrate, Cadmium chloride 2.5-hydrate
Molecular Formula:CdCl2·2.5H2O
Physical Properties:White crystalline powder, odourless, slightly hygroscopic, efflorescent in dry air. Relative density about 3.33. It begins to lose water of crystallisation at 34 °C; after dehydration it becomes anhydrous cadmium chloride, melting at about 568 °C and boiling at about 960 °C. Easily soluble in water, slightly soluble in ethanol and methanol, insoluble in ether. The aqueous solution is neutral or weakly acidic.
Uses:This product is an analytical reagent, widely used in the preparation of cadmium salts and cadmium electroplating baths, as well as in the production of nickel-cadmium batteries, phosphors, pigments and photographic materials. In analytical chemistry, it is used as a precipitating agent, a complex-forming agent and a standard reagent for cadmium ions.
Technical Specifications:
Purity (as CdCl2·2.5H2O) ≥99%
Grade: Analytical reagent (AR)
Implemented standard: GB/T 1285-1994
Appearance: white crystalline
Packaging: 25 kg
