What is caustic soda? Is caustic soda alkali?

Its solid, also known as caustic soda, caustic soda, flake soda, caustic soda, etc., is a white solid, absorbent, can be used as a desiccant, and is easy to deliquescent in the air (the phenomenon of dissolving due to water absorption, which is a physical change); It dissolves in water and releases a lot of heat at the same time.

The liquid is a colorless, astringent and creamy liquid.

Sodium (Na) is element 11 in the periodic table, located in the third period of group a (main group) of the periodic table, and belongs to the alkali metal group [1] (all elements in this group are strongly alkaline, except for hydrogen (h)). Its extranuclear electronic configuration is (1s2,2s2,2p6,3s1), and the outermost 3s1 electron is its valence electron, and the na element easily loses 3s1 electrons to form positive monovalent sodium ions (Na+), so it is strongly metallic. Na element reacts with water (when reacting with water, a beaker should be used and a glass sheet should be covered on the beaker, and the sodium block floats on the water surface during the reaction, melts into a ball, swims on the water surface, has a "hiss" sound, and there is a splash of products), generates a strong alkaline NaOH solution, and releases hydrogen.

In solid NaOH, OH is covalently bonded with O-H, and NA and OH are bound with strong ionic bonds, and its dissociation degree is nearly 100% when dissolved in water, so its aqueous solution is strongly alkaline, which can make the colorless phenolphthalein test solution turn red, or make the pH test paper, purple litmus solution, etc. turn blue.

Pure anhydrous sodium hydroxide is a white, translucent, crystalline solid. Sodium hydroxide is very soluble in water, the solubility increases with the increase of temperature, and a large amount of heat can be released when dissolved, and the concentration of saturated solution can reach 1 at 288K).

Its aqueous solution has an astringent taste and a smooth feeling, and the solution is strongly alkaline, with all the common properties of alkali. There are two kinds of caustic soda on the market: solid caustic soda is white, block-like, flake-like, rod-like, granular, and brittle; Pure liquid caustic soda is a colorless and transparent liquid.

Sodium hydroxide is also soluble in ethanol and glycerol; However, it is insoluble in ether, acetone, and liquid ammonia. It has a corrosive effect on fibers, glass, ceramics, etc., and will release heat when dissolved or diluted with concentrated solution; The neutralization reaction with inorganic acids can also produce a large amount of heat to generate the corresponding salts; Hydrogen is released by reacting with metal aluminum and zinc, non-metal boron and silicon; It disproportionates with halogens such as chlorine, bromine, and iodine. It can precipitate metal ions from aqueous solution to become hydroxides; It can make the oil saponification reaction to generate sodium salt and alcohol of the corresponding organic acid, which is the principle of removing oil stains on the fabric.

It is sodium hydroxide, which is also a chemical product with a wide range of uses, and can also be used to produce soaps and detergents, etc., with the chemical formula NaOH

Sodium hydroxide, with the chemical formula NaOH, commonly known as caustic soda, caustic soda, caustic soda, is a strong alkali with strong corrosiveness, generally in the form of flakes or granules, soluble in water (exothermic when dissolved in water) and forms an alkaline solution, and deliquescent, easy to absorb water vapor and carbon dioxide in the air. NaOH is one of the essential chemicals in chemical laboratories and one of the common chemicals. Pure products are colorless and transparent crystals.

Density. Melting point. Boiling Point: 1390

Industrial products contain small amounts of sodium chloride and sodium carbonate, which are white opaque crystals. There are blocks, sheets, granules and rods, etc. Chemical formula, sodium hydroxide can be used as an alkaline cleaning agent in water treatment, soluble in ethanol and glycerol; Insoluble in propanol, ether.

It also has a corrosive effect on sodium carbon at high temperatures. It disproportionates with halogens such as chlorine, bromine, and iodine. It neutralizes with acids to form salt and water.

The scientific name of caustic soda is sodium hydroxide, which is an inorganic compound with the chemical formula NaOH, also known as caustic soda, solid soda, caustic soda, and caustic soda. Caustic soda has strong alkalinity and strong corrosiveness, and can be used as acid neutralizer, masking agent, precipitating agent, precipitation masking agent, chromogenic agent, saponifying agent, peeling agent, detergent, etc., and is widely used.

Caustic soda, whose scientific name is sodium hydroxide, is a strong alkali with strong corrosive properties. It is generally in the form of flakes or lumps, which is easily soluble in water and forms an alkaline solution. Caustic soda, whose scientific name is sodium hydroxide, is a strong alkali with strong corrosive properties.

It is generally in the form of flakes or lumps, which is easily soluble in water and forms an alkaline solution. Caustic soda is widely used in various sectors such as soap making, textile, printing and dyeing, bleaching, papermaking, petroleum refining, metallurgy and other chemical industries. Because caustic soda has strong water absorption and deliquescent, it can also be used as an alkaline desiccant.

Caustic soda is also used in the production of various detergents, and today's laundry detergents are also made in large quantities. The raw material of papermaking is wood or grass plants, and the addition of dilute caustic soda solution can dissolve and separate the non-cellulose components, so as to make pulp with cellulose as the main component. In the textile industry, sodium hydroxide is used for the treatment and dyeing of fibers, and for the mercerizing of cotton fibers.

Caustic soda is sodium hydroxide, the chemical formula is NAOH, commonly known as caustic soda, caustic soda, caustic soda, is a strong alkali with strong corrosiveness, generally in the form of flakes or blocks, soluble in water and forms an alkaline solution, and deliquescent, easy to absorb water vapor and carbon dioxide in the air, can be added to test whether it is deteriorated. NaOH is one of the essential chemicals in chemical laboratories and one of the common chemicals.

Caustic soda is an industrial alkali with a strong corrosive effect, which can effectively remove dirt and oxides from the wok. aqui te amo。

Caustic soda, caustic soda is the common name for sodium hydroxide, and the chemical is for Naoh. Caustic soda is very alkaline and corrosive, so it should not be used as a cleaning agent. It will corrode pots and pans, etc.

[1]

There are two methods for industrial production of sodium hydroxide: causticizing and electrolysis. The causticizing method is divided into soda ash causticizing method and trona causticizing method according to different raw materials; The electrolysis method can be divided into the separator electrolysis method and the ion exchange membrane method.

Caustic soda is sodium hydroxide, which is a corrosive chemical product, and some people call it caustic soda.

When caustic soda comes into contact with the eye, 85 percent of them can cause permanent blindness.

If accidentally ingested, it will cause irreversible damage to the internal organs of the body, and even fatal.

Sodium hydroxide can corrode most organic matter, so it should be stored with care.

"Caustic soda" is alkali. Caustic soda is a white crystal at room temperature and is highly corrosive. Soluble in water, its aqueous solution is strongly alkaline, and its solution can be used as a washing liquid. Soda ash is salt, not alkali, but the solution is alkaline.
