Custom properties
Nature:
Pure anhydrous sodium hydroxide is a white translucent, crystalline solid. Strong corrosive, absorbent, can be used as a desiccant, but can not dry sulfur dioxide, carbon dioxide and hydrogen chloride gas. And in the air is easy to delix, sodium hydroxide is very soluble in water, solubility increases with the increase of temperature, dissolution can release a lot of heat, 288K of its saturated solution concentration can reach 16.4mol/L(1:1). Its aqueous solution is astringent and greasy, and the solution is strongly basic, with all the commonness of a base. There are two kinds of solid and liquid caustic soda on the market: pure solid caustic soda is white, block, flake, rod, granule Chemicalbook shape, crisp quality; Pure liquid caustic soda is a colorless transparent liquid. Sodium hydroxide is also soluble in ethanol and glycerol; But insoluble in ether, acetone, liquid ammonia. It corrodes fibers, skin, glass, ceramics, etc., and releases heat when dissolved or diluted by concentrated solution. The neutralization reaction with inorganic acid can also generate a large amount of heat and generate the corresponding salts. Hydrogen is produced by reaction with aluminum and zinc, boron and silicon. Disproportionation reaction occurs with halogens such as chlorine, bromine and iodine. Can precipitate metal ions from aqueous solution into hydroxide; Can make the grease saponification reaction, generate the corresponding organic acid sodium salt and alcohol, this is the principle of removing the oil on the fabric.
Colour: white
Material:liquid
Function:
Sodium hydroxide has a wide range of uses, in chemical experiments, in addition to being used as a reagent, because it has a strong hygroscopic property, can also be used as an alkaline desiccant. Caustic soda is widely used in the national economy and is needed in many industrial sectors. The sector that uses caustic soda the most is the manufacture of chemicals, followed by the manufacture of paper, aluminium, tungsten, rayon, cotton and soap. In addition, in the production of dyes, plastics, pharmaceutical and organic intermediates, the regeneration of old rubber, metal sodium, water electrolysis and inorganic salt production, to make borax, chromium salt, manganese salt, phosphate, etc., also want to use a lot of caustic soda. In industry, sodium hydroxide is usually called caustic soda, or caustic soda, caustic soda.
