| [Chemical Properties]
Chromic sulfate is a peach colored solid or red to violet, odorless powder. | [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(10101-53-8) is noncombustible. The primary hazard of this material is the potential for environmental damage if released. Immediate steps should be taken to limit its spread to the environment. | [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. | [Air & Water Reactions]
Water soluble. | [Health Hazard]
INHALATION: Corrosive action on mucous membranes. SKIN: May elicit an allergic reaction. Corrosive action on skin. Lesions confined to exposed parts. | [Potential Exposure]
This compound is used in green paints, inks, dyes, and ceramics | [Fire Hazard]
Special Hazards of Combustion Products: Decomposes to chromic acid when heated. | [First aid]
If this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least 15 minutes, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts the skin, remove contaminated clothing and wash immediately with soap and water. Seek medical attention immediately. If this chemical has been inhaled, remove from exposure, begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR if heart action has stopped. Transfer promptly to a Medical facility. When this chemical has been swallowed, get medical attention. Give large quantities of water and induce vomiting. Do not make an unconscious person vomit. | [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. | [Description]
Chromic sulfate is a peach-colored solid or redto violet, odorless powder. Molecular weight =392.18.Hazard Identification (based on NFPA-704 M RatingSystem): Health 1, Flammability 0, Reactivity 0. Insolublein water | [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. | [storage]
Color Code—Green: General storage may be used.Prior to working with chromic sulfate you should be trainedon its proper handling and storage. Store in tightly closedcontainers in a cool, well-ventilated area away from strongoxidizers and sources of heat. |
| Questions And Answer | Back Directory | [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
