Inorganic Compound Pure anhydrous sodium hydroxide is white semitransparent, crystalline solid. Sodium hydroxide is very easy to dissolve in water, Inorganic Compound the solubility increases with the increase of temperature, can release a lot of heat when dissolving. Its aqueous solution has the astringent and the creamy feeling, the solution assumes the strong alkaline, has the alkali all the generality. There are two kinds of solid and liquid caustic soda: pure solid caustic soda is white, with blocky, flaky, Inorganic Compound rod-shaped, granular, brittle; pure liquid caustic soda is colorless transparent liquid. Sodium hydroxide is also soluble in ethanol, glycerin, but insoluble in ether, Inorganic Compound acetone, liquid ammonia. Corrosive action on fiber, skin, glass, Inorganic Compound ceramics, etc. heat is released when diluted with dissolved or concentrated solution, and reaction with inorganic acid can produce a large amount of heat, produce corresponding salts, and react with metal aluminum and zinc, nonmetal boron and silicon to release hydrogen; It can precipitate the metal ions from aqueous solution to become hydroxide, Inorganic Compound and can make the oil saponification reaction, produce the corresponding organic acid sodium salt and alcohol, this is the principle of removing the oil from the fabric.
The nomenclature of inorganic compounds shall aim at concise and precise representations of the composition and structure of the named substance. Inorganic Compound This requires the use of the name of the element, root or base to express the composition of the substance, and the "chemical preposition" (the function of the noun) to express the connection of each component in the substance.
Colorless odorless gas, sour, soluble in water (volume ratio 1:1), part of the formation of carbonic acid. The gas carbon dioxide is used in alkali-making industry and sugar industry, Inorganic Compound and is used for quenching of steel castings and manufacture of lead and white. Can be burned by carbon in the excessive air or the marble, limestone, dolomite calcined or with acid effect, is the lime, fermentation and other industries by-products. Carbon dioxide generally does not burn and does not support combustion, at room temperature density than air slightly larger, heated expansion will be gathered in the top, often used as a fire extinguishing agent. Inorganic Compound Carbon dioxide is an indispensable raw material for green plant photosynthesis, which is commonly used as fertilizer in greenhouse. Solid carbon dioxide, commonly known as dry ice, can absorb a lot of heat when sublimated, and thus used as a refrigerant, such as artificial rainfall, and often used in the choreography to make smoke.
Inorganic compounds. Generally refers to the elements of carbon elements other than the compound, such as water, salt, sulfuric acid, lime and so on. But some simple carbon-containing compounds such as carbon monoxide, carbon dioxide, carbonic acid, carbonate, and carbide are also studied as inorganic materials because their composition and properties are similar to inorganic substances. The vast majority of inorganic substances can be classified into oxides, acids, alkalis, salt four categorie
