How to Prepare Copper (2 +) Difluoride
The method of making copper (II) difluoride is often to co-heat copper powder or copper oxide with anhydrous hydrofluoric acid. The details are as follows:
Take pure copper powder and place it in a high temperature resistant reactor. Slowly inject anhydrous hydrofluoric acid, and the amount of the two should be measured by stoichiometry. Then heat up to a moderate temperature, about hundreds of tens of degrees Celsius, and continue to stir, so that the two are fully in contact. The copper powder reacts with hydrofluoric acid, and the copper loses two electrons to form copper (II) ions, which are complexed with fluorine ions to produce copper (II) copper difluoride. The reaction formula can be expressed as: Cu + 2HF → CuF 2 + H 2 ↑.
If you replace it with copper oxide, you can also get it. First take the copper oxide powder, put it in a special container, and also inject anhydrous hydrofluoric acid. After a little heating, the copper oxide is phased with hydrofluoric acid. The copper in the copper oxide is positive divalent, and it combines with the fluoride ion in the hydrofluoric acid to form copper (II) copper difluoride, and it is aquatic. The reaction formula is: CuO + 2HF → CuF -2 + H 2O O.
When preparing, pay attention to everything. First, anhydrous hydrofluoric acid is highly corrosive and toxic. It should be handled with care and must be done in a well-ventilated place. And the operator should prepare protective equipment to avoid hurting the body and skin and inhaling poisonous gases. Second, the control of temperature is of paramount importance. If it is too high, the reaction will be too fast or cause an accident. If it is too low, the reaction will be slow and time-consuming. Third, the reactor must resist the corrosion of hydrofluoric acid, often made of special glass or plastic. In this way, pure copper (II) copper difluoride can be obtained.
What are the Physical Properties of Copper (2 +) Difluoride?
The copper (ⅱ) difluoride compound, that is, copper difluoride ($CuF_ {2} $), has unique physical properties.
Viewed, copper difluoride is in the shape of a green powder. This is its external appearance, which is easy to see. Its density is about 4.23 g/cm3. This value represents the mass of its unit volume and reflects the tight arrangement of particles inside the substance.
As for the melting point, it is about 950 degrees Celsius. At this temperature, copper difluoride maintains a solid state, and when it reaches this melting point, it begins to transition to a liquid state, which is a key node for the change of the state of matter. In terms of boiling point, about 1100 degrees Celsius, at this temperature, liquid copper difluoride will transform into a gaseous state, completing another important state transition.
Copper difluoride is soluble in water, and this property allows it to disperse and form a solution in an aqueous environment. And its hygroscopicity is quite strong, making it easy to absorb water from the air. This property requires attention in storage and other links. Because of its physical properties, copper difluoride can play an important role in fields such as ceramic coloring and fluorination agents.
