Product Description:
Aluminum ammonium sulfate typically exists as a white, crystalline powder. It has a characteristic taste and is highly soluble in water. Chemically, it is a double salt composed of aluminum sulfate and ammonium sulfate. When dissolved in water, it dissociates into aluminum ions, ammonium ions, and sulfate ions, endowing it with diverse applications. In the food industry, it is used as a food additive, often in baking powders. It reacts with baking soda to release carbon dioxide gas during baking, helping dough and batters to rise. In water treatment, similar to aluminum sulfate, it can act as a coagulant. It facilitates the aggregation of suspended particles in water, promoting flocculation and sedimentation, thus purifying water. In the textile industry, it can be used as a mordant, assisting in the binding of dyes to fabrics and enhancing colorfastness. Additionally, it has applications in leather tanning, where it helps in the process of converting raw hides into leather. However, safety considerations are important. Ingestion of large amounts may be harmful due to the presence of aluminum and ammonium ions. Inhalation of its dust can cause respiratory irritation. Skin and eye contact should also be avoided as it may cause irritation. It should be stored in a cool, dry place, away from moisture and substances that could react with it to maintain its integrity and effectiveness.

 

Application: 

Aluminum ammonium sulfate has various applications. In the food industry, it's used as a food additive in baking powders, reacting with baking soda to make dough rise. In water treatment, it acts as a coagulant to purify water by aggregating suspended particles. In the textile industry, it serves as a mordant for better dye - fabric binding. It's also used in leather tanning. But be cautious: large - amount ingestion can be harmful, and its dust may irritate the respiratory system, while skin and eye contact should be avoided.
