Hygroscopic, moisture sensitive. 3., umgearb. Similarly, dissolution of chrome alloys gives chromium sulfate together with ferrous sulfate. Additionally, ill-defined but commercially important "basic chromium sulfates" are known.

Il …

The hydrated salts of chromium sulfate can also be produced, albeit impure, by extraction of various other chromium compounds, but these routes are not economically viable.. Band III. Chrom (3+)sulfid (2: 3) ... (2:3) [ACD/IUPAC Name] Sulfure de chrome(3 +) (3:2) [French] [ACD/IUPAC Name] 12018-22-3 [RN ] 234 ... chromium sulfide (C r2S3) Chromium(III) sulfi de. Extraction of chromite ore with sulfuric acid in the presence of some chromate gives solutions of chromium(III) sulfate contaminated with other metal ions. Keep the container tightly closed in a dry and well-ventilated place. dichromium trisulph ide. DICHROMIUM(3+) ION TRISULFANEDIIDE. La solubilité est exprimée en général en grammes de soluté par cent grammes de solvant.. Cette liste répertorie les solubilités dans l’eau (en g/100 g d'eau) de substances salines en fonction de la température, sous une pression d'une atmosphère.

According to X-ray crystallography, its is a combination of that of nickel arsenide (1:1 stoichiometry) and Cd(OH)2 (1:2 stoichiometry).

Seule l'utilisation d'un instrument de mesure permet de l'identifier et d'en quantifier la concentration.

Anthroquinone and quinone are produced on large scale by treatment of anthracene and phenol with chromic acid. Chromium(III) Sulfide is the inorganic compound with the formula Cr2S3. Chromium(III) Sulfide is the inorganic compound with the formula Cr 2 S 3. Chromium(III) sulfate usually refers to the inorganic compounds with the formula Cr2(SO4)3.x(H2O), where x can range from 0 to 18. It is important to fully reduce the hexavalent chromium to trivalent since the hexavalent is more likely to cause health problems for tanners and leather consumers.

Evaporation of these acidic solutions affords the hydrate salt described above.

It is also used in preparation of chromium metal, dye, in printing and dyeing industry. Covington, A. D.; Lampard, G. S.; Menderes, O.; Chadwick, A. V.; Rafeletos, G.; O'Brien, P. "Extended X-ray absorption fine structure studies of the role of chromium in leather tanning" Polyhedron 2001, volume 20, 461–466. Jellinek, F. "The structures of the Chromium Sulphides" Acta Crystallographica 1957, volume 10, p620-p628.

Auflage. [3], Except where otherwise noted, data are given for materials in their. It is involved in the preparation of chrome catalyst. It can be synthesized by reacting sulfur dioxide with potassium dichromate (dissolved in sulfuric acid) at -38°C. Evaporation of these acidic solutions affords the hydrate salt described … Le sulfate de chrome (III) anhydre est un solide poudreux de couleur pêche.

It is a brown-black solid. [Cr+3] The most useful source of chromium(III) sulfate are the Cr(III) wastes from the chromate oxidation of various organic compounds. Ce produit est inodore.

Chromium(III) potassium sulfate dodecahydrate (Potassium chromium(III) sulfate dodecahydrate, Chrome alum) is widely used chemical in dyeing and textile industry. The most useful source of chromium(III) sulfate are the Cr(III) wastes from the chromate oxidation of various organic compounds. Enke, Stuttgart 1981. Most important commercially is basic chromium sulfate, which is thought to be [Cr2(H2O)6(OH)4]SO4 (CAS#39380-78-4).
