R42/43:May cause sensitization by inhalation and skin contact. 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).Ĭobalt sulfate is reasonably anticipated to be a human carcinogenbased on sufficient evidence of carcinogenicity from studies in experimental animals. 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 heptahydrate crystallises below 44o and is efflorescent with m 97o. It contains a cobalt(2+).Ĭrystallise it three times from conductivity water (1.3mL/g) between 100o and 0o depending on which hydrate is required. All federal, state, and local environmental regulations must be observed.ĬhEBI: Cobalt(2+) sulfate is a compound of cobalt and sulfate in which the ratio of cobalt (+2 oxidation state) to sulfate is 1:1.

Use a licensed professional waste disposal service to dispose of this material. The sulphate is believed like the alums to contain the 3+ ion. The hydrated sulphate also has a small positive magnetic susceptibility. and the ammonium alum has a moment of 2.1 B.M. The potassium alum is diamagnetic, the rubidium salt has a magnetic moment less than 1 B.M. Cobalt(III) alums MCo(SO4)2.12H2O (M = K, Rb, Cs or NH4) can be isolated as blue crystals from the mixed cooler solutions of the two sulphates in dilute sulphuric acid. It is stable in the dry state, but is decomposed by water with evolution of oxygen it is fairly stable in solution in dilute sulphuric acid. The blue, crystalline hydrate Co2(SO4)3.18H2O is prepared by the oxidation of cobalt(II) sulphate in 8N sulphuric acid either electrolytically or chemically with ozone or fluorine. May react as either oxidizing agents or reducing agents UN3288 Toxic solids, inorganic, n.o.s., Hazard Class: 6.1 Labels: 6.1-Poisonous materials, Technical Name Required.Īqueous solution reacts with bases, generating some heat. Ensure that medical personnel are aware of the material(s) involved and take precautions to protect themselves. In case of contact with substance, immediately flush skin or eyes with running water for at least 20 minutes. Remove and isolate contaminated clothing and shoes. Administer oxygen if breathing is difficult. Give artificial respiration if victim is not breathing. Special Hazards of Combustion Products: Toxic cobalt oxide fumes may form in fire. Many be used to catalyze organic reactions. Contact with eyes or skin causes irritation. Inhalation causes shortness of breath and coughing permanent disability may occur. Many of these compounds catalyze organic reactions. They usually do not react as either oxidizing agents or reducing agents but such behavior is not impossible. These neutralizations generate heat, but less or far less than is generated by neutralization of inorganic acids, inorganic oxoacids, and carboxylic acid. The resulting solutions contain moderate concentrations of hydrogen ions and have pH's of less than 7.0. Sinks and mixes with water.Īcidic salts, such as COBALT SULFATE(1), are generally soluble in water.
