Potassium Dichromate (CAT: R071305) is a bright orange-red crystalline solid known for its strong oxidizing properties. It is commonly used in analytical chemistry, organic synthesis, and industrial applications such as electroplating, metal passivation, and dye manufacturing. In laboratories, potassium dichromate is employed as a reagent for oxidizing alcohols to ketones or carboxylic acids and in chromic acid cleaning solutions. It is highly soluble in water, forming a strongly acidic and corrosive solution.
