Product Description

Reagent Grade Ammonium Sulphate with crystal

1.Chemical name: Ammonium sulphate
2.Molecular formula: (NH4)2SO4
3.Molecular weight: 132.14
4.Cas No.: 7783-20-2

5.Character: It is colorless transparent orthorhombic crystal, deliquescent. Relative density is 1.769(50ºC). It's soluble in water(At 0ºC, solubility is 70.6g/100mLwater; 100ºC, 103.8g/100mLwater). Aqueous solution is acidic. It's insoluble in ethanol, acetone or ammonia. It reacts with the alkalies to form ammonia. 
6.Usage: According to GB 2760-2011, it could be used as processing aid (only used as nutrient for fermentation). It also could be used as dough regulator and yeast food. In fresh yeast production, it's the nitrogen source for yeast cultivation (Dosage is not specified.). Dosage is about 10% (about 0.25% for wheat powder) for yeast nutrient in bread.
 7.Packing: It is packed with polyethylene bag as inner layer, and a compound plastic woven bag as outer layer. The net weight of each bag is 25kg.
8.Storage and transport: It should be stored in a dry and ventilative warehouse.kept away from water and moisture during transport. Unload with care so as to avoid damaged. Furthermore. it must be stored separately from poisonlus substances.
