Description

Potassium Dichromate, also known as Potassium Bichromate, Dipotassium Dichromate, and Dichromic Acid-Dipotassium salt, has the chemical formula K2Cr2O7 or Cr2K2O7. It appears as orange to red crystalline powder or granules with no odor and a bitter metallic taste. It is partly soluble in Water but insoluble in Alcohol at ambient conditions. On an industrial scale, it is produced by roasting chrome ore with potassium carbonate. It is also preferably produced by reacting sodium dichromate with potassium chloride. Upon exposure, Potassium dichromate can severely irritate the eyes and respiratory tract. It is a known human carcinogen and may cause cancer of the lungs or sino-nasal cavity upon long-term exposure. Lab grade chemicals possess reasonable purity but do not comply with any official standard for quality or purity like the ACS Grade, the USP Grade, or the FCC Grade. The Lab Grade is also known as Laboratory Reagent (LR) and Chemically Pure (CP). Lab Alley’s Potassium Dichromate, Lab Grade is recommended for educational institutes, research labs, and commercial applications. Lab Alley is selling its premium quality products online at laballey.com in the United States of America (USA).

What Is Potassium Dichromate? 

It's well known that the chemical element potassium is very important for a wide variety of biological functions in the human body. However, the chemical compound potassium dichromate is quite the opposite - it is very harmful to our health. Potassium dichromate is a chemical compound typically used as an inorganic chemical reagent for industrial and laboratory processes. As we will see, this chemical is used to produce an array of products ranging from shoe polishes and glues to paints and waxes. Read more here.

Information On Potassium Dichromate From Wikipedia

Potassium dichromate, K2Cr2O7, 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. It is a crystalline ionic solid with a very bright, red-orange color. The salt is popular in the laboratory because it is not deliquescent, in contrast to the more industrially relevant salt sodium dichromate. Read more here.

Potassium Dichromate For UV Calibration

Answer. The use of Potassium Dichromate solvated in dilute Perchloric acid is an established and well recognised method for the validation of the absorbance scale and linearity of a spectrophotometer in the UV region.

Potassium Dichromate For Woodworking 

Greg Williams: Mix 1 tsp. of potassium dichromate powder per quart of cold water, and apply evenly to the wood. Allow the wood to dry thoroughly, and apply a fast evaporating solvent such as alcohol to the surface to determine if the color is what you desire. Read more here.

Potassium Dichromate Hazards

Potassium Dichromate may cause an asthma-like allergy. Future exposure can cause asthma attacks with shortness of breath, wheezing, coughing, and/or chest tightness. Potassium Dichromate may damage the liver and kidneys. Read more here.

Potassium Dichromate Structure [Potassium Dichromate: Definition, Formula & Uses - Video] 

The molecular formula is K2Cr2O7. Physical properties of potassium dichromate include a reddish-brown color (as a solid) and a molecular weight of 294.18 grams per mole. Potassium dichromate is also known as a hexavalent chromium compound, and the oxidation state of chromium is 6+. Read more here.

Potassium Dichromate + Sulphuric Acid 

The oxidising agent used in these reactions is normally a solution of sodium or potassium dichromate(VI) acidified with dilute sulphuric acid. If oxidation occurs, the orange solution containing the dichromate(VI) ions is reduced to a green solution containing chromium(III) ions. Read more here.
