summarize
Chemical formula NaOH, is a highly corrosive alkali, generally white flake or particle, can be miscible with water to form an alkaline solution, and can also be dissolved and ethanol. This alkali is deliquescent and absorbs water vapor from the air, as well as acidic gases such as carbon dioxide. It is one of the commonly used chemicals. It is widely used and necessary for many industrial processes: it is often used in the manufacture of wood pulp paper, textiles, soap and other cleaners, etc., and it is also used in household alkaline drainage supplies.
nature
Pure anhydrous It is a white translucent, crystalline solid. It is strongly corrosive and absorbent, and can be used as a desiccant, but it cannot dry , carbon dioxide and hydrogen chloride gases. It is easily deliquable in air, and Itis easily soluble in water, and its solubility increases with the increase of temperature. It can release a lot of heat when dissolved, and the saturated solution concentration of 28Chemicalbook8K can reach 16.4mol/L(1:1). Its aqueous solution is astringent and greasy, and the solution is strongly alkaline, with all the commonness of alkali. There are two kinds on the market: solid is white, block, flake, rod, granular, brittle; Pure liquid is colorless transparent liquid. It is also soluble in ethanol and glycerol. But insoluble in ether,
liquid . Corrodes fibers, skin, glass, ceramics, etc., and releases heat when dissolved or diluted in concentrated solution; The neutralization reaction with inorganic acid can also produce a lot of heat and generate the corresponding salts. React with aluminum and zinc, non-metallic boron and silicon to release hydrogen; Disproportionation reaction occurs with halogens such as chlorineand iodine. Can precipitate metal ions from aqueous solution to become hydroxide; It can make the oil saponification reaction, generate the corresponding organic acid sodium salt and alcohol, which is the principle of removing the oil on the fabric.
