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.
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.

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.
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.
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.
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.
