What are the physical properties of lanthanum (III) trifluoride?

Long (III), what are the physical properties of the Sanjiang compound? And listen to me for you.

Sanjiang compound, its color may be different. Or it is a clear color, like a clear spring in the mountains, transparent and bottomless, without the slightest disturbance of impurities, the view is clear to the mind; or it is colorful, like clouds in the sky, gorgeous and colorful, attracting the viewer's heart to marvel.

Its quality varies. Or it is a solid state, as solid as a rock, although it has gone through wind and rain, its shape is difficult to change, and it can be a good material for building houses and bridges; or it is a liquid state, soft as boneless, flowing with the trend, square when it encounters a square, round when it encounters a circle, and can moisten all things in silence; or it is a gaseous state, ethereal and invisible, like the breeze in the sky, coming and going without a trace, but it can be felt agile.

Furthermore, the density of the three rivers is also different. The heavy ones sink to the bottom, like the genus of lead stone, which is stable and thick; the light ones float on the top, like the generation of red hair, light and elegant.

As for its melting point and boiling point, it also varies from object to object. There are those with extremely low melting points, which melt when they are warm, just like spring snow meets the sun, which is fleeting; there are those with extremely high boiling points, which need to be burned for a long time before they can see their gasification state.

Its conductivity is also divided into advantages and disadvantages. Those who are good at conducting electricity, such as copper and iron, can pass through the current without obstruction, which can be the way of electricity; those who are insulated, such as the genus of wood and stone, cannot be invaded by current, which can ensure safety.

These are all the general physical properties of the Sanjiang compound, but everything in the world changes endlessly. To know the details, it is still necessary to study it carefully.

Is Lanthanum (III) Trifluoride Chemically Stable?

Long (III) asked: "Are the chemical properties of trihalides stable?"

said: "The chemical properties of trihalides cannot be generalized and their stability cannot be generalized. The trihalides formed by different elements have different properties.

If the trihalides of boron, such as boron trifluoride, boron trichloride, etc., although the electrons in the valence layer of the central boron atom do not reach the octet structure, their stability is enhanced by the formation of p-dπ bonds between the empty d orbital of the halogen atom and the empty p orbital of boron. However, these compounds still have strong Lewis acidity, which is easy to react with substances with solitary pair electrons, so the stability is not very high.

Aluminum tri-halide, taking aluminum trichloride as an example, is ionic crystal in solid state and dimer in gaseous state. Under normal conditions, it is more stable than boron tri-halide. When exposed to water, due to the hydrolysis of aluminum ions, it will react violently to form aluminum hydroxide and corresponding hydrogen halide, which is not stable in humid environments.

Phosphorus tri-halide, such as phosphorus trichloride, has relatively active chemical properties. Among them, phosphorus atoms have lone pairs of electrons and can be used as nucleophiles to participate in many reactions. And it is easy to be oxidized. When exposed to water, it will also undergo hydrolysis reaction to form phosphoric acid and corresponding hydrogen halide, so the stability is also limited. < Br >
In summary, the chemical stability of trihalides varies depending on the specific compound, and is mostly affected by the electronic structure, oxidation state, bonding method, and external environment of the central atom. It cannot be simply asserted that they are stable or unstable. "

What are the preparation methods of lanthanum (III) trifluoride?

There are various methods for causing trichloride of growth (III). One is the direct combination of metal and chlorine. If iron is used as an example to make iron burn in chlorine, the text says: "When iron encounters chlorine, it burns and emits a huge light, produces brown smoke, and forms iron trichloride. The formula is: $2Fe + 3Cl_ {2}\ stackrel {ignite }{=\!=\!=} 2FeCl_ {3} $." This is because chlorine has strong oxidizing properties and can oxidize iron to + 3 valence.

The second is the method of oxidizing with acid. For example, if iron oxide and hydrochloric acid are combined, its words say: "Take a little iron oxide, put it in a container, slowly add hydrochloric acid, see its gradual dissolution, the liquid turns yellow, and obtain iron trichloride. The corresponding formula is: $Fe_ {2} O_ {3} + 6HCl = 2FeCl_ {3} + 3H_ {2} O $." This is due to the contact of basic oxides and acids to dissolve salt and water.

The third is the metathesis of salt and acid. In response to iron carbonate and hydrochloric acid, it goes: "Put iron carbonate in the container, drop into hydrochloric acid, there are bubbles, and the solids gradually disappear, the liquid turns yellow, and iron trichloride is obtained. The corresponding formula is: $Fe_ {2} (CO_ {3}) _ {3} + 6HCl = 2FeCl_ {3} + 3H_ {2} O + 3CO_ {2}\ uparrow $. "This is because metathesis requires precipitation, gas or weak electrolyte, which should generate carbon dioxide gas, so that it should work.

There is also a method of combining iron hydroxide with hydrochloric acid. It says:" Take iron hydroxide, add hydrochloric acid, see the precipitation gradually dissolve, the liquid turns yellow, and forms a solution of iron trichloride. The corresponding formula is: $Fe (OH) _ {3} + 3HCl = FeCl_ {3} + 3H_ {2} O $. " This is due to the neutralization of acid and base, ferric hydroxide is a base, hydrochloric acid is an acid, and the two phases are combined to produce salt and water. All these methods can produce trichloride of (III), each with its own suitability, and should be selected according to the situation.

What is the price range of lanthanum (III) trifluoride in the market?

Those who have tasted the world's market have many questions about the price of long (III) trioxide. However, its price is not fixed, and it moves with the changes of the market, making it difficult to determine its wide area.

Looking back at the past, the state of the market is numerous, and the price of goods varies according to time, place, quality and supply and demand. Long (III) trioxide is used in a wide range, either as a manufactured material or as a medical research agent, so its price is also affected by various factors.

In peak times, supply and demand match each other, and its price may be stable at a medium level. If there are many people in need and there are few people in supply, the price will rise; conversely, if the supply exceeds the demand, the price will decline. And the good and bad of its quality is also a variable of the price. For the quality, the price must be higher than that of the regular product.

And the distance to the place, the difficulty of transportation, are all related to the price. Those who are close to the place of origin and convenient to transport, the price may be slightly cheaper; those who are far and difficult to transport, the price will increase its value.

Although it is difficult to determine the range of its price, it is common sense. Under various variables, it shows a dynamic value. Or in the busy part of the city, looking at the past price, measuring the change of supply and demand, you can get its approximate price range, but it is difficult to determine the exact number in the end. The feeling of building the market is changing rapidly.
