Specification

The Cadmium chloride hydrate, with the CAS registry number 7790-78-5, is also known as Cadmium chloride hemipentahydrate. This chemical's molecular formula is CdCl₂·2.5H₂O and molecular weight is 228.35. Its EINECS number is 233-296-7. What's more, its systematic name is bis(dichlorocadmium) pentahydrate. Its classification codes are: (1)Mutation data; (2)Reproductive Effect; (3)Tumor data. It should be sealed and stored in a cool, ventilated and dry place. Moreover, it should be protected from sun and rain. It is used as a reagent to make photographic paper and carbon paper. It is used as analysis reagent, such as hydrogen sulfide gas absorption agent. It is also used in photography, printing and dyeing industries.

Physical properties of Cadmium chloride hydrate are: (1)#H bond acceptors: 5; (2)#H bond donors: 10; (3)#Freely Rotating Bonds: 0; (4)Polar Surface Area: 46.15 Å².

Preparation: anhydrous cadmium chloride can be prepared by the action of anhydrous chlorine or hydrogen chloride gas on heated cadmium metal. Cadmium chloride separates out in crystals from aqueous solution below the temperature of 34 °C, the product CdCl₂·2.5H₂O is got.

When you are using this chemical, please be cautious about it as the following:
This chemical is toxic if swallowed and is very toxic by inhalation. It is toxic as it has a danger of serious damage to health by prolonged exposure through inhalation and if swallowed. It may cause cancer and heritable genetic damage. It may impair fertility and cause harm to the unborn child. What's more, it is very toxic to aquatic organisms as it may cause long-term adverse effects in the aquatic environment. In case of accident or if you feel unwell, you must seek medical advice immediately (show the label where possible). It should be avoided exposure that you need obtain special instructions before use. This material and its container must be disposed of as hazardous waste. You must avoid releasing it to the environment just refering to special instructions/safety data sheet.
