What are the main uses of neodymium (+ 3) cationic fluoride?
First, in the matter of metallurgy, (+ 3) metallurgy can be used as a catalyst. For example, in the case of metallurgy, it can promote the speed of the reaction and make the recovery of the metal easier. In the past, there were many metallurgy, and the material was reversed, and the quality of the gold obtained was also high. However, if this compound is added, the reaction of the metal is like a flow, and the effect of the gold is greatly increased, and the gold produced is more refined and more refined, which is beneficial for the manufacture of equipment and utensils.
Second, it is also useful in dyeing. It can be used as a mordant to help dye materials. In ancient times of dyeing, dyes often fall off easily, and the color is not solid. And with this (+ 3) chemical agent, the dye phase is firmer, and the dyed color lasts longer. It is not easy to fade when washed with water. The beauty of this product is the essence of cotton cloth, which enhances the color because of it. It is more difficult to print and dye.
Third, in terms of performance, it also has its own capabilities. It may help the production of the product, making the product easier to be absorbed by people. The production of the ancient product is often ineffective, and the product is absorbed and utilized by people. And this chemical compound may be able to make the product more transparent, increase the effect of the product, and help save the suffering of patients.
Therefore, (+ 3) has a wide range of uses, and it is important for metallurgical, dyeing, and other industries. It is a great convenience for the ancient people's life and production, and it is a great step to promote general skills.
What are the physical properties of neodymium (+ 3) cationic fluoride?
The physical rationality of the three-dimensional ($In ^ {3 +} $) compound is as follows:
###1. The crystallization of the three-dimensional compound
is polycrystalline. In the case of chlorination ($InCl_ {3} $), its solids are usually. In this case, the $In ^ {3 +} $is encapsulated by chlorine particles, which form a fixed lattice in a specific coordination manner. The atoms of different elements are slightly different due to factors such as semi-melting. For example, the crystals of bromide ($InBr_ {3} $) and iodide ($InI_ {3} $) are chlorinated differently, but they all form an ordered arrangement based on the interaction of the elements of gold.
###2. Melt boiling
Generally speaking, the three compounds have a phase high melting boiling temperature. In the case of chlorination, the melting price is 586 dollars ^ {\ circ} C $. Due to the existence of the reaction of particles, the strong attraction of $In ^ {3 +} $prime particles requires high energy to overcome, which makes the energy required for solidification and liquid melting large. And when the atomic number of molecules increases, the melting temperature changes to a certain extent. Usually, due to the increase of half of the number of molecules, the lattice can be changed, and the melting temperature rises and falls. For example, the molten phase of iodide is chlorinated, and the bromide phase is different. Factors such as the distance between molecules and the lattice energy are closely related.
###3. Solubility
Solubility in water varies. Chloride is soluble in water and dissolves in water: $InCl_ {3}\ rightarrow In ^ {3 + } + 3 Cl ^{-}$ 。 its solubility is due to hydration, $In ^ {3 +} $water molecules form hydrated molecules, and chlorine molecules are also encapsulated by water molecules, so that the dissolution process can proceed independently. The difference in solubility of iodide in water is due to the interaction of $In ^ {3 +} $iodide molecules and the nature of iodide molecules themselves, which makes it difficult to be effectively dispersed and dissolved by water molecules. In the aqueous solution, some ternary compounds also have a certain solubility, such as some soluble compounds containing carbonyl groups, etc., which can form a certain interaction, so that the ternary compounds can be dissolved and dispersed in them.
###4. color
Under normal circumstances, the ternary compounds are mostly colored or white solid. Such as chlorination, bromide, and often white crystals, the iodide may be slightly lighter due to the influence of iodine. Its main color can be different, and it can be determined by the absorption of light in the available light, $In ^ {3 +} $and the chemical monomer. Due to the specific energy difference, the absorbed light is not in the main field of the available light, so it is mostly colored or colored. The characteristics of iodide make the absorbed light slightly offset, showing a light color.
What are the chemical properties of neodymium (+ 3) cationic fluoride?
The chemical properties of mercury (+ 3) cationic halides are particularly specific. Mercury usually shows + 1 and + 2 valence states, and + 3 valence states are rare.
This type of halide has poor stability. Because the outer electron arrangement of + 3-valent mercury ions is relatively unstable, it is prone to electron transfer to tend to a more stable structure. It often shows strong oxidation in chemical reactions. The + 3-valent mercury ions have a strong tendency to obtain electrons to reduce their own valence states and achieve stability.
In aqueous solution, mercury (+ 3) cationic halides may react with water. Water can be used as an electron donor to interact with mercury (+ 3) ions. Mercury (+ 3) ions capture electrons from water, causing water to be oxidized, and the valence state of mercury ions decreases. This process may be accompanied by phenomena such as solution color change and gas escape.
In case of reducing substances, the oxidation of mercury (+ 3) cationic halides is complete. Reductive species such as active metal elementals and low-priced compounds are prone to react with mercury (+ 3) cationic halides. Mercury ions gain electrons, and the valence state decreases, while the reducing substances lose electrons and increase the valence state. These reaction rates may vary depending on the properties, concentration, temperature, etc. of the reactants.
Mercury (+ 3) cationic halides also tend to hydrolyze. Halogen ions in water or in synergy with mercury (+ 3) ions promote hydrolysis reactions. The hydrolysis products are either related species of mercury hydroxide (+ 3), or other mercury compounds are formed due to further reactions.
In general, mercury (+ 3) cationic halides are prone to various reactions in different environments due to their special valence states and active chemical properties. They are characterized by significant oxidation in chemical reactions and lack of stability.
What are the preparation methods of neodymium (+ 3) cationic fluoride?
There are several ways to make bismuth (+ 3) cationic halides.
First, bismuth powder is directly combined with halogen elements. If bismuth reacts with chlorine, bismuth powder burns violently in chlorine gas, and the flame is pale, to obtain bismuth trichloride: Bi + 3Cl ³\ (\ stackrel {ignited }{=\!=\!=}\) 2BiCl
. This reaction is violent, and it needs to be in a well-ventilated environment and pay attention to safety protection to prevent chlorine from escaping and hurting people.
Second, bismuth oxide reacts with hydrohalic acid. If bismuth trioxide interacts with hydrochloric acid, a bismuth trichloride solution can be obtained: Bi (NO) 2O + 6HCl = 2BiCl (+ 3H) O. During the reaction, bismuth trioxide is slowly added to a container containing hydrochloric acid and stirred moderately to promote a sufficient reaction. However, it should be noted that bismuth salts are easy to hydrolyze. In order to inhibit hydrolysis, an appropriate amount of corresponding acid can be added to the solution.
Third, bismuth salts are used for metathesis reaction with halides. If bismuth nitrate solution is mixed with sodium chloride solution, bismuth chloride precipitation can be precipitated: Bi (NO) 😉 + 3NaCl = BiCl (+ 3NaNO). During operation, slowly mix the two solutions and stir from time to time to promote complete precipitation. After that, through filtration, washing, drying and other steps, pure bismuth chloride can be obtained.
Preparation of bismuth (+ 3) cationic halide, according to the actual situation, considering the availability of raw materials, the difficulty of reaction conditions, product purity requirements and other factors, choose the appropriate method.
