Potassium dichromate can be made by oxidation of potassium hydroxide and chromium(III) oxide. It can also be made by adding an acid to potassium chromate. Occurrence. It is very rarely found in the earth. It is only found in very dry areas. If it rains, it dissolves in the water and is washed away. Uses
This page looks at the oxidation of alcohols using acidified sodium or potassium dichromate(VI) solution. This reaction is used to make aldehydes, ketones and carboxylic acids, and as a way of distinguishing between primary, secondary and tertiary alcohols. Important! It is pointless reading this ...
Solutions are prepared from solid potassium dichromate, NIST SRM 935a. 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.
