Water - colorless, tasteless, transparent liquid, can be used for drinking, cleaning, agricultural watering, hydroelectric power generation, etc.

Salt - white solid, easily soluble in water, salty, can be used as a condiment, antiseptic, chemical raw materials<

Sucrose--white solid, easily soluble in water, sweet flavor, can be used as a condiment, beverage

Copper wire--purple-red solid, easy to conduct electricity, easy to bend, can be used as wires, electrical appliances

Expanded Information:

In life, practical copper wire is used as a conductor. Conductivity is very good, a large number of used in the manufacture of wires, cables, brushes, etc.; good thermal conductivity, commonly used in the manufacture of anti-magnetic interference with magnetic instruments, instruments, such as compasses, aeronautical instrumentation, etc.; plasticity is very good, easy to hot and cold pressure processing, can be made into tubes, rods, wires, strips, strips, strips, plates, foils, etc. Copper material. Pure copper products are smelted and processed products.

Sucrose, that is, table sugar, a kind of disaccharide, by a molecule of glucose hemiacetal hydroxyl and a molecule of fructose hemiacetal hydroxyl with each other condensed dehydration and become. Sucrose is sweet, odorless, soluble in water and glycerol, and slightly soluble in alcohol.

Relative density 1.587 (25 ℃). It has a spinning property, but has no change of spinning effect. Sucrose is almost universally found in the leaves, flowers, stems, seeds and fruits of the plant kingdom. It is particularly abundant in sugar cane, sugar beets and maple sap. Sucrose has a sweet taste and is an important food and sweet flavoring. It is divided into white granulated sugar, red granulated sugar, white sugar, rock sugar and coarse sugar (yellow sugar).

Sucrose is very soluble in water, its solubility increases with the increase in temperature, dissolved in water is not conductive. Sucrose is also soluble in aniline, azobenzene, ethyl acetate, amyl acetate, molten phenol, liquid ammonia, alcohol-water mixtures and acetone-water mixtures, but not soluble in gasoline, petroleum, anhydrous alcohol, trichloromethane, carbon tetrachloride, carbon disulfide and turpentine and other organic solvents.

Sucrose is a crystalline substance. The specific gravity of pure sucrose crystals is 1.5879, and the specific gravity of sucrose solution varies according to the concentration and temperature. The specific gravity of sucrose is +66.3° to +67.0°.

Salts are a class of compounds in which metal ions or ammonium ions (NH4+) combine with acid ions or non-metal ions. Such as sodium chloride, calcium nitrate, ferrous sulfate and ammonium acetate calcium sulfate, copper chloride, sodium acetate, etc. Generally speaking, salt is the product of complex decomposition reactions, salt and salt reaction to generate new salt and new salt, salt and base reaction to generate new salt and new base, salt and acid reaction to generate new salt and new acid, such as sulfuric acid and sodium hydroxide to generate sodium sulfate and water, sodium chloride and silver nitrate to generate silver chloride and sodium nitrate reaction.

There are also other reactions that produce salts, such as replacement reactions. Soluble salt solution has conductivity, because there are free swimming ions in the solution, so it can be used as an electrolyte. Hydrochloric acid is both an important product of the salt chemical industry and an important raw material for the production of silicon materials. Salt is a type of crystal.
