Chromium Potassium Sulfate, scientifically known as Potassium Chromium Sulfate dodecahydrate, is a double salt of chromium and potassium with the chemical formula KCr(SO4)2·12H2O. This compound, often appearing as violet-red crystals, is a subject of interest for chemists and material scientists due to its unique properties and synthesis pathways. NINGBO INNO PHARMCHEM CO.,LTD. specializes in providing high-purity chemicals, ensuring that our clients receive compounds that meet stringent quality standards for their research and industrial applications. Understanding the science behind Chrome Alum is key to its effective utilization.

The physical properties of Chromium Potassium Sulfate are noteworthy. It is characterized by its distinct violet-red crystalline appearance and is soluble in water, with a solubility of approximately 244g per 100g of water at 25°C. The dodecahydrate form has a density of around 1.842 g/cm³. Unlike some other alums, Chromium Potassium Sulfate crystals can be efflorescent, meaning they may lose water molecules when exposed to air, potentially forming harder chunks. Proper storage in hermetic vessels is therefore recommended to maintain its integrity.

Several synthesis routes can be employed to produce Chromium Potassium Sulfate. One common method involves the reaction of potassium sulfate with chromium(III) sulfate. Another pathway utilizes potassium dichromate, sulfuric acid, and a reducing agent such as ethanol or oxalic acid. These synthesis processes are crucial for achieving the desired purity and crystal form for various applications, from industrial tanning to laboratory crystal growth. The choice of synthesis method often depends on the required purity level and the scale of production.

The stability of Chromium Potassium Sulfate is also an important consideration. While it is generally stable under normal conditions, it is sensitive to heat. The dodecahydrate form decomposes around 89°C, and the anhydrous form at higher temperatures. Handling this chemical requires adherence to safety protocols, as indicated by its hazard symbols which typically denote irritation. As a responsible chemical supplier, NINGBO INNO PHARMCHEM CO.,LTD. provides comprehensive safety data sheets (SDS) to guide proper handling and storage practices.
