Sodium hydroxide English alias: Caustic Soda Flakes, Sodium Hydrate??Caustic Soda??Lye Molecular formula: NaOH CAS No.: 1310-73-2 EINECS: 215-185-5 Molecular weight: 40.00 Appearance: White crystalline powder Solubility (mg/L): Easily soluble in water, ethanol, glycerol, insoluble in acetone, ether Relative density(water=1): 2.13g/cm3 Melting point: 318.4 ?? Chemical property: Sodium hydroxide is corrosive to fibers, skin, glass, ceramics, etc. It gives off heat when dissolved or diluted in concentrated solution; neutralization reaction with inorganic acid can also generate a lot of heat to produce corresponding salts; reaction with metal aluminum and zinc, non-metal boron and silicon, etc. gives off hydrogen; disproportionation reaction with halogens such as chlorine, bromine and iodine. It can precipitate metal ions from aqueous solution to become hydroxide; it can make saponification reaction of grease to produce sodium salt and alcohol of corresponding organic acid, and thus re... |
