二硝酸カドミウム

化学的特性

White, amorphous pieces or hygro- scopic needles. Soluble in water, ammonia, and alco- hol.

物理的性質

White crystal or amorphous powder; hygroscopic; density 3.60 g/cm3; melts at 350°C; very soluble in water, also soluble in alcohols.

使用

Cadmium salts, photographic emulsions, col- oring glass and porcelain, laboratory reagent, cad- mium salts.

製造方法

reparation Cadmium nitrate is prepared by dissolving cadmium metal or its oxide, hydroxide, or carbonate, in nitric acid followed by crystallization:
CdO + 2HNO₃ → Cd(NO₃)₂ + H₂O.

定義

ChEBI: An inorganic nitrate salt having Cd(2+) as the counterion.

一般的な説明

Odorless white solid. Sinks in water.

空気と水の反応

Water soluble.

反応プロフィール

Mixtures of metal/nonmetal nitrates with alkyl esters may explode, owing to the formation of alkyl nitrates; mixtures a nitrate with phosphorus, tin (II) chloride, or other reducing agents may react explosively [Bretherick 1979 p. 108-109].

危険性

Dangerous fire and explosion hazard.

健康ハザード

Inhalation of fumes can produce coughing, chest constriction, headache, nausea, vomiting, pneumonitis. Chronic poisoning is characterized by emphysema and kidney injury. Ingestion causes gastrointestinal disturbance and severe toxic symptoms; both kidney and liver injuries may occur. Contact with eyes causes irritation.

安全性プロファイル

Confirmed human carcinogen. Poison by ingestion and possibly other routes. Moderately toxic by inhalation. Mutation data reported. When heated to decomposition it emits very toxic fumes of Cd and NOx. See also CADMIUM COMPOUNDS and NITRATES.
