About this item

IUPAC name	dipotassium;oxido-(oxido(dioxo)chromio)oxy-dioxochromium
inchi	InChI=1S/2Cr.2K.7O/q;;2+1;;;;;;2-1
inchi key	KMUONIBRACKNSN-UHFFFAOYSA-N
molecular formula	K2Cr2O7
synonyms	POTASSIUM DICHROMATE 7778-50-9 Potassium bichromate Kaliumdichromat Iopezite
Compound Description	Potassium bichromate appears as orange red crystals. Denser than water and soluble in water. No distinctive odor. May severely irritate the eyes and respiratory tract. Avoid contact with organic materials. Noncombustible. Used in pyrotehnic displays with tungsten and iron. Potassium dichromate is a potassium salt that is the dipotassium salt of dichromic acid. It has a role as an oxidising agent, an allergen and a sensitiser. It contains a dichromate. Potassium Dichromate is an orange to red colored, crystalline, inorganic compound that emits toxic chromium fumes upon heating. Potassium dichromate is highly corrosive and is a strong oxidizing agent. This substance is used in wood preservatives, in the manufacture of pigments and in photomechanical processes, but is mainly replaced by sodium dichromate. Potassium dichromate primarily affects the respiratory tract causing ulcerations, shortness of breath, bronchitis, pneumonia and asthma but can also affect the gastrointestinal tract, liver, kidneys and immune system. This substance is a known human carcinogen and is associated with an increased risk of developing lung cancer and cancer of the sinonasal cavity. Potassium dichromate is a chemical compound of potassium and hexavalent chromium. It is a common inorganic chemical reagent and is also used in photography and wood treatment. It is found naturally as the mineral lopezite. Hexavalent chromium refers to chemical compounds that contain the element chromium in the +6 oxidation state. Chromium is more toxic than other oxidation states of the chromium atom because of its greater ability to enter cells and higher redox potential. Chromic acid , dipotassium salt. A compound having bright orange-red crystals and used in dyeing, staining, tanning leather, as bleach, oxidizer, depolarizer for dry cells, etc. Medically it has been used externally as an astringent, antiseptic, and caustic. When taken internally, it is a corrosive poison. See also: Dichromate ion ; Eucalyptus globulus leaf; potassium dichromate ... View More ...
