Sodium hydroxide? The chemical formula is NaOH, commonly known as caustic soda, caustic soda, caustic soda, which is a kind of strong corrosiveness? Strong alkali is usually flaky or blocky, which is easily soluble in water (exothermic when dissolved in water) and forms an alkaline solution. Deliquescence, easy to absorb water vapor (deliquescence) and carbon dioxide (deterioration) in the air, and hydrochloric acid can be added to check whether it is deteriorated.
NaOH is? Chemical laboratory is one of the essential chemicals and one of the common chemicals. Pure products are colorless and transparent crystals. The density is 2. 1.30g/cm? . The melting point is 365438 08.4℃. The boiling point is 1390℃.
Do industrial products contain a small amount? Sodium chloride and? Sodium carbonate is a white opaque crystal. There are blocks, sheets, granules and rods. The formula is 39.997.
Sodium hydroxide can be used as an alkaline cleaning agent in water treatment, soluble in ethanol and glycerol; Insoluble in propanol and ether. With chlorine, bromine, iodine and other halogens? Unbalanced. Neutralization with acid produces salt and water.
Add soda ash, caustic soda and? Refined barium chloride preparation removes impurities such as calcium, magnesium and sulfate ions, and then adds it into a clarifier. Accelerated precipitation with sodium polyacrylate or causticized wheat bran, sand filtration, neutralization with hydrochloric acid, preheating with brine, electrolysis, preheating and evaporation of electrolyte, salt cooling to obtain liquid caustic soda, and further concentration to obtain solid caustic soda. Salt mud washing water is used to melt salt.
