Sulfuric acid, ammonium chromium(3+) salt (2:1:1), dodecahydrate

Description:
Sulfuric acid, ammonium chromium(3+) salt (2:1:1), dodecahydrate, commonly referred to as ammonium chromium sulfate dodecahydrate, is an inorganic compound with the formula (NH4)2Cr2(SO4)3·12H2O. This compound typically appears as a greenish crystalline solid and is highly soluble in water. It is characterized by its acidic properties due to the presence of sulfate ions and can act as a source of chromium ions in various chemical reactions. The dodecahydrate form indicates that it contains twelve water molecules per formula unit, contributing to its stability and solubility. This compound is often used in various applications, including dyeing, tanning, and as a mordant in textile industries. Additionally, it has roles in analytical chemistry and as a catalyst in certain reactions. However, due to the presence of chromium, it is important to handle this substance with care, as chromium compounds can be toxic and pose environmental hazards. Proper safety measures should be observed when working with this chemical.
