What are the physical and chemical properties of chromium fluoride tetrahydrate

Chromium (III) fluoride tetrahydrate (Chromium (III) Fluoride Tetrahydrate), its chemical composition is $CrF_ {3}\ cdot4H_ {2} O $. The properties of this substance are mostly light green to blue-green crystals or powders.

In terms of its physical properties, first of all, it has a certain color, light green to blue-green appearance, and under light, the color is warm. It is in the form of crystals or powders, and the powders are fine and loose; the crystals have regular geometric shapes, or are prismatic or bulk, and the crystal surface is flat and shiny.

In addition, the density is relatively fixed, which is its inherent property and is related to the degree of close arrangement of particles inside the substance. The value of density makes its volume in a specific container in a fixed proportion to its mass.

Solubility is also an important physical property. In water, chromium (III) fluoride tetrahydrate has a limited degree of solubility, only a small amount can be dissolved, and the solution is weak in color. Due to the interaction between ions, it is difficult to completely dissolve in water.

Its melting point is quite high, and a higher temperature is required to make it from solid to liquid. At high temperatures, the lattice structure is gradually destroyed, the particles are able to break free, and the material form changes.

These physical properties are closely related to the internal structure of the material. The interaction between ionic bonds and water molecules jointly determines its color and solubility; the size of the lattice energy dominates the melting point, density and other properties.

How to prepare chromium fluoride tetrahydrate

To prepare chromium (ⅲ) fluorinated tetrahydrate, the following method is required.

First take an appropriate amount of chromium salts, such as chromium chloride (ⅲ), which is a readily available starting material. Place it in a clean container, dissolve it in an appropriate amount of pure water, and stir until it is fully dissolved into a homogeneous solution. This step is intended to uniformly disperse the chromium salt ions in the liquid phase.

Next take an appropriate amount of hydrofluoric acid and slowly drop it into the above chromium salt solution. Caution must be used when adding dropwise, because hydrofluoric acid is corrosive. Continue to stir during the dropwise addition process to make the two fully react. The principle of the reaction is that chromium ions combine with fluoride ions to form chromium (ⅲ) fluoride precipitation.

After the reaction is completed, a precipitate is formed in the resulting mixture system. The mixture is filtered with filter paper or a suitable filter device to separate the precipitate. The precipitate is the crude product of chromium (ⅲ) fluoride.

However, this crude product still contains impurities, and needs to be washed with pure water many times to remove unreacted ions and other impurities. After washing, the precipitate is moved to a suitable container and placed in a low-temperature drying equipment. Control the temperature and time to allow the precipitate to dry moderately, while retaining its tetramolecular crystal water, and finally obtain the finished product of chromium (ⅲ) fluoride tetrahydrate. The whole process must pay attention to the safety of operation, work in a well-ventilated place, and strictly control the conditions of each step to obtain a pure target product.
