질산 코발트 C화학적 특성, 용도, 생산
화학적 성질
Red crystals. Deliquescent in moist air. Soluble in most organic solvents.물리적 성질
The hexahydrate is red monoclinic crystal; deliquescent in moist air; density 1.87 g/cm3; decomposes at 55°C, losing three molecules of water; decomposes to green cobalt(II) oxide on further heating at 74°C; very soluble in water (134 g/100mL at 0°C); also soluble in alcohols and acetone. The anhydrous salt is pale red powder; density 2.49 g/cm3; decomposes around 100°C; soluble in water.용도
Sympathetic inks, cobalt pigments, catalysts, additive to soils and animal feeds, vitamin preparations, hair dyes, porcelain decoration.정의
ChEBI: A cobalt salt in which the cobalt metal is in the +2 oxidation state and the counter-anion is nitrate.제조 방법
Cobalt(II) nitrate is prepared by treating the metal, or its oxide, hydroxide or carbonate with dilute nitric acid. The solution on evaporation yields red crystals of hexahydrate:Co + 2HNO3 → Co(NO3)2 + H2
Co(OH)2+ 2HNO3 → Co(NO3)2 + 2H2O
CoCO3+ 2HNO3→ Co(NO3)2 + CO2 + H2O.
일반 설명
Odorless red solid. Sinks and mixes with water.공기와 물의 반응
Water soluble.반응 프로필
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].위험도
Oxidizing agent, dangerous fire risk in contact with organic materials.건강위험
Inhalation causes shortness of breath and coughing; permanent disability may occur. Ingestion causes pain and vomiting. Contact with eyes or skin causes irritation.질산 코발트 준비 용품 및 원자재
