Description
- General description: Chromium(III) potassium sulfate dodecahydrate (Potassium chromium(III) sulfate dodecahydrate, Chrome alum) is a violet colored solid. It has been synthesized by reacting sulfur dioxide with potassium dichromate (diisolved in sulfuric acid) at -38°C. It is widely used chemical in dyeing and textile industry.[1]
- Application: Chromium(III) potassium sulfate dodecahydrate (KCr(SO4)2.12H2O) may be used for coating the slides for microscopic studies on Periplaneta americana.[2][3] It may be used in the preparation of quasi-monodisperse spherical core-shell particles of Cr/α-Cr2O3.[4]
