황산코발트 C화학적 특성, 용도, 생산
화학적 성질
Cobalt sulphate appears as pink or red crystals. It is stable, non-flammable, and hygroscopic and undergoes dehydration at 41°C and 71°C.용도
Usual source of water-soluble cobalt since it is the most economical and it shows less tendency to deliquesc or dehydrate than the chloride or nitrate. Used in storage batteries; in Co-electroplating baths; as drier for lithographic inks, varnishes; in ceramics, enamels, glazes to prevent discoloring; in Co pigments for decorating porcelain.정의
ChEBI: A hydrate that is the heptahydrate form of cobalt(2+) sulfate.일반 설명
Pink to red monoclinic prismatic crystals or red granular solid. Odorless. Becomes anhydrous at 788°F.공기와 물의 반응
Water soluble. The resulting solution is acidic.반응 프로필
Does not react strongly as either oxidizing agents or reducing agents but such behavior is not impossible. The aqueous solutions are acidic. May catalyze organic reactions.화재위험
Literature sources indicate that Cobalt sulfate heptahydrate is nonflammable.잠재적 노출
Many be used to catalyze organic reactions.운송 방법
UN3288 Toxic solids, inorganic, n.o.s., Hazard Class: 6.1; Labels: 6.1-Poisonous materials, Technical Name Required.Purification Methods
Crystallise it three times from conductivity water (1.3mL/g) between 100o and 0o depending on which hydrate is required. The heptahydrate crystallises below 44o and is efflorescent with m 97o . Between 44o and 70o the monoclinic hexahydrate CoSO4.6H2O m 41.5o is formed, and above 70o the monohydrate CoSO4.H2O m 71o is obtained. The pale reddish or lavender-coloured anhydrous salt is obtained by heating the hydrate above 250o, boiling with conc H2SO4 or heating with (NH4)2SO4).비 호환성
Aqueous solution reacts with bases, generating some heat. May react as either oxidizing agents or reducing agents폐기물 처리
