Chromic sulfate Chemical Properties,Usage,Production

  • Physical Properties Reddish-brown hexagonal crystal; the pentadecahydrate is a dark green amorphous substance while the octadecahydrate is a violet cubic crystal; the densities are 3.10 g/cm3 (the anhydrous salt), 1.87 g/cm3 (pentadecahydrate), 1.709/cm3 (octadecahydrate); the anhydrous sulfate is insoluble in water and acids; the hydrate salts are soluble in water; the pentadecahydrate is insoluble in alcohol, but the octadecahydrate dissolves in alcohol.
  • Uses Chromium(III) sulfate is used as the electrolyte for obtaining pure chromium metal. It is used for chrome plating of other metals for protective and decorative purposes. Other important applications of this compound are as a mordant in the textile industry; in tanning leather; to dissolve gelatin; to impart green color to paints, varnishes, inks, and ceramic glazes; and as a catalyst.
  • Preparation Chromium(III) sulfate is prepared by treating chromium(III) hydroxide with sulfuric acid followed by crystallization:
    2Cr(OH)3 + 3H2SO4 → Cr2(SO4)3 + 6H2O
  • Chemical Properties Also known as chromic sulfate,Cr2(S04)3, is a violet or red powder that is insoluble in water and acids.The basic form (reduction of sodium dichromate) is used in tanning. Other uses are chrome plating,chromium alloys,mordant,catalyst,green paints and varnishes,green ink,and ceramic glazes.
  • Chemical Properties Chromic sulfate is a peach colored solid or red to violet, odorless powder.
  • Uses Chrome plating, chromium alloys, mordant, catalyst, green paints and varnishes, green ink, ceramics (glazes). The basic form (reduction of sodium dichromate) is used in tanning.
  • Definition ChEBI: A compound of chromium and sulfate in which the ratio of chromium (in the +3 oxidation state) to sulfate is 2:3
  • General Description Dark green to violet crystalline material. Used in paints and inks, ceramics, and in textile dyeing. I Chromic sulfate is noncombustible. The primary hazard of Chromic sulfate is the potential for environmental damage if released. Immediate steps should be taken to limit its spread to the environment.
  • Air & Water Reactions Water soluble.
  • Reactivity Profile Chromic sulfate has weak oxidizing or reducing powers. Redox reactions can however still occur. The majority of compounds in this class are slightly soluble or insoluble in water. If soluble in water, then the solutions are usually neither strongly acidic nor strongly basic. These compounds are not water-reactive.
  • Health Hazard INHALATION: Corrosive action on mucous membranes. SKIN: May elicit an allergic reaction. Corrosive action on skin. Lesions confined to exposed parts.
  • Fire Hazard Special Hazards of Combustion Products: Decomposes to chromic acid when heated.
  • Potential Exposure This compound is used in green paints, inks, dyes, and ceramics
  • Shipping UN3077 Environmentally hazardous substances, solid, n.o.s., Hazard class: 9; Labels: 9-Miscellaneous hazardous material, Technical Name Required
  • Incompatibilities This chemical has weak oxidizing and reducing properties. Keep away from strong oxidizers Chromic Sulfate 837 (perchlorates, peroxides, permanganates, chlorates, nitrates, chlorine, bromine, and fluorine). When heated this chemical decomposes to chromic acid.
  • Waste Disposal Return to supplier where possible. Where this is not practical, the material should be encapsulated and buried in a specially designated chemical landfill.
