Potassium dichromate is a chemical reagent that is inorganic in nature. It is used as an oxidising agent in many chemical reactions in laboratories. Potassium dichromate K 2 Cr 2 O 7 is a solid crystalline ionic with a bright, reddish-orange colour. It has a wide range of applications as an oxidising agent in laboratories and industries. It is very hazardous and chronic to health as all hexavalent chromium compounds.

K2cr2o7

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. It is a crystalline ionic solid with a very bright, red-orange color. The salt is popular in laboratories because it is not deliquescent , in contrast to the more industrially relevant salt sodium dichromate. Potassium dichromate is usually prepared by the reaction of potassium chloride on sodium dichromate. Alternatively, it can be also obtained from potassium chromate by roasting chromite ore with potassium hydroxide. It is soluble in water and in the dissolution process it ionizes:. Potassium dichromate is an oxidising agent in organic chemistry , and is milder than potassium permanganate. It is used to oxidize alcohols. It converts primary alcohols into aldehydes and, under more forcing conditions, into carboxylic acids. In contrast, potassium permanganate tends to give carboxylic acids as the sole products. Secondary alcohols are converted into ketones. For example, menthone may be prepared by oxidation of menthol with acidified dichromate. In an aqueous solution the color change exhibited can be used to test for distinguishing aldehydes from ketones. This color change arises because the aldehyde can be oxidized to the corresponding carboxylic acid.
