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.
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.
