CAS number : 7647-14-5
Molecular weight :58.44
Molecular formula/chemical symbol :NaCl
Description :
Apearances: Colorless cubic crystals or white crystalline. Solubility: soluble in water. Solubility in water: room temperature (25 ° C) under each 100g soluble about 36.2g, very slightly soluble in ethanol, NaCl can form colloids dispersed in alcohol, its solubility in water is reduced due to the presence of hydrochloric acid, almost insoluble in concentrated hydrochloric acid. Slight deliquescence in the air.
USES :
Used
in the manufacture of soda ash and caustic soda and other chemical products,
ore smelting. The food industry and fisheries for salting, and can also be used
as raw materials and refined salt seasonings.
Keywords:Surface treatment chemicals
