It can be made by reacting cobalt, cobalt(II) oxide, or cobalt(II) hydroxide with sulfuric acid. It is very rarely found in the earth. Uses. It is used as a pigment. It is also used to make other cobalt salts. It can be used in electroplating cobalt. It was added to beer in the past but that poisoned people. Enthalpy of formation of solid at standard conditions Data from NIST Standard Reference Database NIST Chemistry WebBook The National Institute of Standards and Technology (NIST) uses its best efforts to deliver a high quality copy of the Database and to verify that the data contained therein have been selected on the basis of sound.

Carcinogenicity: Cobalt and its compounds have been shown to cause cancer in laboratory animals. Carcinogenicity Data: *NTP Carcinogen* Ingredient CAS# Known Anticipated IARC Category Cobalt Sulfate No No 2B. The chemical formula for cobalt(III) sulfate is Co2(SO4)3. The Co represents cobalt, the S represents sulfur, and the O represents oxygen. One atom of sulfur and four atoms of oxygen together represent sulfate. The formula indicates that one molecule of cobalt(III) sulfate contains two atoms of cobalt, three atoms of sulfur and 12 atoms of oxygen.

Hydrated cobalt(II) sulfate is used in the preparation of pigments, as well as in the manufacture of other cobalt salts. Cobalt pigment is used in porcelains and glass. Cobalt(II) sulfate is used in storage batteries and electroplating baths, sympathetic inks, and as an additive to soils and animal feeds.
For these purposes, the cobalt sulfate Appearance: reddish crystalline (anhydrous, monohydrate), pink salt (hexahydrate). Reactions and stereochemistry of thiolato and sulfenato cobalt complexes produced a ca.
mixture of A-[ Co(en)₂PenS]⁺. Both isomers underwent oxidation by H₂O₂ to form sulfenato and sulfinato complexes. The complexes [ Co(CyS)₃]³⁻ and [Co(PenS)₂]⁻ also reacted readily with H₂O₂, producing sulfenato and sulfinato Author: Daniel L.
Herting. Sulfinatometal complexes exhibit unusual features in their structure, preparation, and use, and have attracted rapidly growing interest.
Their structures are determined by the ability of the RSO group both to act as a monodentate ligand (sulfinato‐S or sulfinato‐O) and to add to coordination centers as a bidentate ligand, either intramolecularly or intermolecularly, via the two oxygens.
P.V. Bernhardt, G.A. Lawrance, in Comprehensive Coordination Chemistry II, (iii) Thiolates. Thiolates are strong ligands and a rich coordination chemistry with cobalt(III) exists. Normally, thiols are employed directly in synthesis, and this is the usual entry into their coordination chemistry.
The formation of the red trinuclear complexes is favoured by milder conditions, such as refluxing in cyclohexane for Thiolates are strong ligands and a rich coordination chemistry with cobalt(III) exists.

As part of our work on models of the iron(III) site of Fe-containing nitrile hydratase, a designed ligand PyPSH4 with two carboxamide and two thiolate donor groups has been synthesized.
Reaction of (Et4N)[FeCl4] with the deprotonated form of the ligand in DMF affords the mononuclear iron(III) complex (Et4N)[FeIII(PyPS)] (1) in high yield.

Sulfinol solvent is a composite solvent, consisting of a mixture of diisopropanolamine (%) or methyl diethanolamine (MDEA), sulfolane (tetrahydrothiophene dioxide) (%), and water (%).
The acid gas loading of the Sulfinol solvent is higher and the energy required for its regeneration is lower than those of purely chemical solvents. A novel route to phase formation of cobalt oxyhydrates using KMnO 4 as an oxidizing agent C.-J.
