What are the Physical Properties of Cobalt (2 +) Difluoride?
Cobalt (ⅱ) difluoride, that is, cobalt fluoride ($CoF_ {2} $), has many physical properties. Its color is light red to pink, like the light red of peach blossoms in spring, and it feels soft. This is due to the ion arrangement and electron transition in the crystal structure, which allows specific wavelengths of light to be absorbed and reflected, resulting in this unique color.
Cobalt fluoride is solid and has a solid texture. It is as stable as Mount Tai at room temperature, just like the cornerstone of an ancient castle. Its melting point is quite high, about 1200 ° C, and it can be melted at a high temperature like a fire. It can be made into steel after being tempered. The boiling point is also very high, reaching 1400 ° C, and it can remain stable in high temperature environments.
Its density is about 4.43 g/cm ³, and it feels like it is sinking in the hand, as if it is holding the weight of the years. Slightly soluble in water, only slightly dissolved in water, like a hermit maintaining independence in the world.
The crystal structure of cobalt fluoride belongs to the tetragonal crystal system, and the atoms are arranged in an orderly manner, like a rigorous army phalanx. The lattice parameters are specific, a = 0.4685 nm, c = 0.3085 nm, and this precise structure gives it unique physical and chemical properties.
Under light, cobalt fluoride has certain optical properties, and it has absorption and transmission characteristics for specific wavelengths of light. It can be used in optical materials and other fields, like a clever dancer of light, to deduce a unique optical melody. It has a characteristic absorption peak in the infrared spectral region, which can be used as a "fingerprint" for analysis and identification.
What are the Chemical Properties of Cobalt (2 +) Difluoride?
Cobalt (ⅱ) cobalt difluoride ($CoF_ {2} $) has unique properties and is of great interest to explore. This substance is an inorganic compound, which is light red powder at room temperature, resembling the light red of the morning glow, and has an attractive color.
In terms of its chemical properties, $CoF_ {2} $has certain stability. In case of strong oxidizing agents, it will also change. In high temperature conditions, it can react with some active metals, just like a warrior in a high temperature furnace. For example, when heated with sodium metal, the activity of sodium will replace cobalt from its fluoride. This is a wonderful chemical transformation, like a "game" between elements.
Furthermore, $CoF_ {2} $is soluble in acid, just like ice and snow blending into warm currents. In hydrochloric acid, cobalt (II) salts and hydrofluoric acid are formed, and this reaction quietly changes the form of matter. At the same time, although its solubility in water is limited, it is not without movement. In the slightly soluble state, some $CoF_ {2} $will ionize cobalt ions and fluoride ions, and start the "active journey" of ions in the microscopic world. The chemical properties of
$CoF_ {2} $are reflected in many fields. In the field of material synthesis, it is like a silent "behind-the-scenes hero", who can act as a catalyst or participate in the preparation of special functional materials, help the development of materials science, and write a wonderful chapter on the stage of chemistry with its unique properties.
What are the Preparation Methods of Cobalt (2 +) Difluoride?
Cobalt (ⅱ) cobalt difluoride, that is, $CoF_2 $, the method of preparation, about a few ends.
First, hydrofluoric acid can be used to react with cobalt hydroxide. With the liquid of hydrofluoric acid, slowly drop into the suspension of cobalt hydroxide, during which the temperature of the reaction should be controlled, so as not to overplay. Hydrofluoric acid is highly corrosive, and it must be protected when handling. The reaction formula is as follows: $Co (OH) _2 + 2HF\ longrightarrow CoF_2 + 2H_2O $. After the reaction is completed, the precipitation of $CoF_2 $is obtained by filtration, and then it is washed with water to remove its impurities. After drying, the pure $CoF_2 $can be obtained.
Second, cobalt carbonate can react with hydrofluoric acid. Take the powder of cobalt carbonate and pour it into hydrofluoric acid gradually, also pay attention to temperature control. The reaction of cobalt carbonate and hydrofluoric acid is as follows: $CoCO_3 + 2HF\ longrightarrow CoF_2 + H_2O + CO_2 ↑ $. The reaction is completed, and the product is filtered, washed and dried according to the previous method to obtain $CoF_2 $.
Third, cobalt oxide is prepared by reacting with hydrofluoric acid. When cobalt oxide meets hydrofluoric acid, it also produces $CoF_2 $. The reaction equation is: $CoO + 2HF\ longrightarrow CoF_2 + H_2O $. Similarly, after subsequent filtration, washing and drying steps, the product is pure and usable.
When preparing $CoF_2 $, because the reagents used are corrosive, and the reaction or gas escapes, it must be handled in a well-ventilated place, and the necessary protective equipment should be applied to protect personal safety.
