Potassium dichromate - Wikipedia
Potassium dichromate, K 2 Cr 2 O 7, is a common inorganic chemical reagent, most commonly used as an oxidizing agent in various laboratory and industrial applications. As with all hexavalent chromium compounds, it is acutely and chronically harmful to health.
Potassium Dichromate | K2Cr2O7 | CID 24502 - PubChem
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.
Potassium dichromate ACS reagent, = 99.0 7778-50-9
Potassium dichromate is a red-orange colored solid. Its crystals belong to the triclinic crystal system. On heating above 600°C, it decomposes to give oxygen, potassium chromate and chromium(III) oxide. It acts as a strong oxidizing agent in acidic media. It can be synthesized by the fusion of chromium(III) oxide with potassium carbonate and ...
Potassium Dichromate - Preparation, Properties, Formula, …
Potassium dichromate, also referred to as potassium salt, is the dipotassium salt of dichromic acid. The preparation of potassium dichromate is commonly done by using chromates, and these chromates are formed by the reaction of chromite ore with sodium/potassium carbonate.
