Details

Chromium Potassium Sulfate Granular Reagent Grade

Chromium Potassium Sulfate, also known as Chrome Alum and Potassium Chromium(III) Sulfate Dodecahydrate, has the chemical formula CrK(SO 4 ) 2 •12H 2 O. It appears as purple hygroscopic solid at room temperature. It is odorless and slightly soluble in water at ambient conditions. It is normally produced by reacting potassium dichromate with sulfuric acid at -38°C. Chemicals in the Reagent Grade category have high purity and are best suited for analytical purposes.
