Sodium hydroxide

Sodium hydroxide (NaOH), commonly known as caustic soda, caustic soda, caustic soda, caustic soda and because another name in Hong Kong called Ge Shi, and at room temperature is a white crystalline solid with a strong corrosive. Soluble in water, its solution is strongly alkaline, can phenolphthalein red. Sodium hydroxide is a very common base, is one of the essential drugs chemistry laboratories. Its solution can be used as washing liquid. CASRN: 1310-73-2 EINECS Registry Number: 215-185-5 sodium hydroxide used in a very wide use in chemical experiments, in addition to the reagent used outside, because it has a strong water absorption, but also with do alkaline desiccant. Sodium hydroxide is widely applied in the national economy, many industrial sectors need sodium hydroxide. Sodium hydroxide is the most used chemicals manufacturing sector, followed by paper, aluminum, tungsten refining, rayon, rayon and soap manufacturing. In addition, in the production of dyes, plastics, pharmaceutical and organic intermediates, the regeneration of the old rubber, made of metal sodium, water electrolysis as well as inorganic salt production, preparation of borax, chromium salts, manganese, phosphate, etc., should use a lot of soda. Hydroxide for industrial use should be in line with national standards GB 209-2006; industrial ion-exchange membrane caustic soda should meet the national standard GB / T 11199-89; fiber with sodium hydroxide should be in line with national standards GB 11212-89; edible hydrogen sodium oxide should meet the national standard GB 5175-85. Photosynthetic experiments to absorb carbon dioxide.
