Potassium Dichromate Potassium dichromate is one of the most widely used chemical reagents in inorganic chemistry. It primarily serves as a strong oxidising agent in various chemical reactions in laboratories and industries. Potassium dichromate is an important chemical widely used wherever oxidation is involved. It is also one of the most important compounds of chromium. Potassium dichromate is always handled with great precautions and care as it poses health hazards to humans if exposed for a long time. It has a very bright red-orange colour appearance and is found in an ionic solid crystalline state. Potassium dichromate is widely used in analytical chemistry and industries as it is non-deliquescent in nature compared to other industrially important salts like 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. We will look at various aspects of potassium dichromate in detail below.

A compound of chromium and one of the most popular chemical reagents in organic chemistry, Potassium dichromate serves as a strong oxidising agent. It helps bring various chemical reactions wherever oxidation is involved in commercial and laboratory settings. The compound is handled with the utmost care because even slight carelessness can lead to hazards. Table of Content • Occurrence of Potassium Dichromate • Formula • Structure • Preparation • Properties • Chemical Properties • Uses • Frequently Asked Questions Occurrence of Potassium Dichromate Potassium dichromate occurs naturally in the form of a rare mineral called lopezite. It is obtained as vug fillings in the Atacama Desert’s nitrate deposits in Chile as well as in the Bushveld igneous complex in South Africa. Potassium Dichromate Formula It is a dipotassium salt of dichromic acid. It contains the following elements: • Potassium • Chromium • Oxygen The potassium dichromate formula is K 2Cr 2O 7. The IUPAC name of K 2Cr 2O 7 is Potassium dichromate(VI). The other names of the compound are as follows: • Potassium dichromate • Potassium bichromate • Bichromate of potash • Chromic acid, dipotassium salt Potassium Dichromate Structure It is an ionic compound containing two potassium cations and a negatively charged dichromate anion. The dichromate has two hexavalent chromium atoms (with a 6+ oxidation state), and they are attached to oxygen atoms. Structure of Potassium Dichromate It contains two ionic bonds between t...

\( \newcommand\) • • • • • • • • • This page looks at the oxidation of alcohols using acidified sodium or potassium dichromate(VI) solution. This reaction is used to make Oxidizing the different types of alcohols The oxidizing agent used in these reactions is normally a solution of sodium or potassium dichromate(VI) acidified with dilute sulfuric acid. If oxidation occurs, then the orange solution containing the dichromate(VI) ions is reduced to a green solution containing chromium(III) ions. The electron-half-equation for this reaction is as follows: \[ Cr_2O_7^ + 7H_2O\] Primary alcohols Primary alcohols can be oxidized to either aldehydes or carboxylic acids, depending on the reaction conditions. In the case of the formation of carboxylic acids, the alcohol is first oxidized to an aldehyde, which is then oxidized further to the acid. An aldehyde is obtained if an excess amount of the alcohol is used, and the aldehyde is distilled off as soon as it forms. An excess of the alcohol means that there is not enough oxidizing agent present to carry out the second stage, and removing the aldehyde as soon as it is formed means that it is not present to be oxidized anyway! If you used ethanol as a typical primary alcohol, you would produce the aldehyde ethanal, \(CH_3CHO\). The full equation for this reaction is fairly complicated, and you need to understand the \[ 3CH_3CH_2OH + Cr_2O_7^ + 7H_2O\] In organic chemistry, simplified versions are often used that concentrate on what i...
