1,Chemical Name: Sodium Carbonate 2,Molecular Formula:CNa2O3 3,Molecular Weight: 105.99 4,CAS: 497-19-8 5,Character: Anhydrous is a white crystalline powder, relative density 2.53, melting point 851 ºC, heated to 400 ºC decomposition. Insoluble in ethanol, soluble in water, dissolved when heat, solution is strongly alkaline. Easily deliquescence agglomeration in the air, absorb CO2 and produce sodium bicarbonate. Monohydrate as a fine white crystal or powder, the relative density of 1.55. Stable at room temperature and heated to lose crystal water becomes anhydrous at 100 ºC. Decahydrate colorless transparent crystallization temperature 34 ºC, relative density (20 ºC) 1.44, in the air easily weathered. 6,Usage: It is one of the important chemical raw materials used in making chemicals, cleaning agents, detergents, but also for photography and manufacturing pharmaceuticals products. 7,Packing: It is packed with polythene bag as the inner layer, and a compound plastic woven bag as the outer layer. The net weight of each bag is 25kg. 8,Storage and Transport: It should be stored in a dark, dry and ventilative warehouse, kept away from water and moisture; unloaded with care to avoid damage. Furthermore, it must be stored separately from poisonous substances.
