Molecular formula:NaOH，Molecular weight:forty.00，Common name:Caustic soda, caustic soda.
nature:Solid products are granular, highly hygroscopic, easily soluble in water, and strongly exothermic white solids when dissolved; We can also provide different concentrations of aqueous solution products according to customer requirements. The aqueous solution is greasy, alkaline and highly corrosive. It has great corrosive force on skin, fabric and paper. It is easy to absorb carbon dioxide from the air and gradually turn into sodium carbonate. genusCategory 8.two inorganic alkaline corrosive articles, UN No.: un18twothree.
Purpose:Mainly used in laboratoryChemical analysis is also used in fine chemical manufacturing and other industrial production with high quality requirements.
