一般描述
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.
应用
Chromium(III) potassium sulfate dodecahydrate (KCr(SO4)2.12H2O) may be used for coating the slides for microscopic studies on Periplaneta americana. It may be used in the preparation of quasi-monodisperse spherical core-shell particles of Cr/α-Cr2O3.
