What are the Physical Properties of Cupric Acetate Monohydrate?

Cupric Acetate Monohydrate, that is, copper acetate monohydrate. Its physical properties are particularly important, and today I will tell you in detail.

Looking at its appearance, copper acetate monohydrate is dark green crystalline, just like emerald carved, crystal clear and elegant, its color is fresh, under the sun, shining, and it is pleasing to the eye.

When it comes to smell, this thing has a slight fragrance of acetic acid, but its taste is peaceful, not pungent, and it does not feel uncomfortable when smelled, but feels fresh.

Its density is about 1.882 g/cm ³. Although the texture is not extremely heavy, it feels solid and thick when held in the hand.

As for solubility, copper acetate monohydrate is quite easy to dissolve in water, and it is placed in clear water. In an instant, it quietly disappears and fuses with water, just like salt in soup, invisible and invisible, resulting in a clear solution. And it also has a certain solubility in alcohols, although it is not as good as water, it can be observed.

Its melting point is about 115 ° C, and it melts when heated. It gradually changes from solid to liquid, and the shape changes very subtly. If heated to a higher temperature, this substance will decompose and not return to its original state, which is the characteristic of its thermal stability.

Furthermore, copper acetate monohydrate is hygroscopic. If placed in a high humidity environment, it absorbs water like a sponge, slowly absorbing water vapor in the air, and its crystal surface may become moist. This is also one end of its physical properties.

Is Cupric Acetate Monohydrate Chemically Stable?

Cupric Acetate Monohydrate, that is, copper acetate monohydrate. The stability of its chemical properties depends on many factors.

Copper acetate monohydrate is generally quite stable at room temperature and pressure. It can be settled in dry air and does not change easily. Looking at its structure, copper ions are supported by acetate ions and crystal water, forming the shape of this compound. This structure makes it stable to a certain extent.

In special circumstances, its stability may be affected. If it is in a high temperature range and reaches a certain temperature, copper acetate monohydrate may decompose. The crystal water will escape first, and then copper acetate may decompose into copper oxide and other products. Furthermore, in case of strong acid, the strong acid ion may interact with the acetate ion, causing the structure of the compound to be broken and the stability to be lost. In case of hydrochloric acid, acetate ion may combine with hydrogen ion to produce acetic acid, while copper ion may form copper chloride with chloride ion.

In humid air, although it is relatively stable, it may be exposed for a long time, or it may react slowly with carbon dioxide in the air, causing its composition to change.

Therefore, under normal conditions of normal temperature, pressure and dryness, the chemical properties of copper acetate monohydrate are still stable. However, special conditions such as high temperature, strong acid, and humidity can damage its stability and undergo chemical changes.

What should be paid attention to when storing Cupric Acetated Monohydrate?

Cupric Acetate Monohydrate, that is, copper acetate monohydrate, when storing, many things need to be paid attention to.

First, it must be placed in a cool and dry place. This is because copper acetate monohydrate is afraid of moisture and moisture, and humid environments can easily cause deliquescence, which in turn damages its purity and quality. If the place where it is stored is heavy with moisture and the water vapor is adsorbed on the drug, over time, it will change the properties of the drug and affect the subsequent use effect.

Second, avoid fire and heat sources. Copper acetate monohydrate is easy to decompose when heated, and its chemical structure is damaged in high temperature environments, and its chemical properties also change. If it is close to a fire or heat source, not only will the drug itself fail, but it may also cause safety risks, such as the generation of harmful gases.

Third, it needs to be sealed and stored. There are many components in the air, such as oxygen, carbon dioxide and water vapor, which may react with copper acetate monohydrate. Sealed storage can effectively isolate the air, slow down its reaction rate with substances in the air, and prolong the shelf life of the drug. For example, oxygen may change the valence state of copper in it, and carbon dioxide and water vapor may interact together to form other compounds.

Fourth, the storage place should be away from reducing substances. Copper acetate monohydrate has a certain degree of oxidation. If it coexists with reducing substances, it is prone to redox reactions and deterioration. Reductive substances such as active metal elements and some compounds containing low-priced elements should not be stored with one or the other.

Fifth, avoid mixing with acidic and basic substances. Acidic substances may convert acetate ions, while basic substances may react with copper ions to form precipitation, which will cause changes in the chemical composition and properties of copper acetate monohydrate and cannot be used normally.

Cupric Acetate Monohydrate Preparation

To make Cupric Acetate Monohydrate (copper acetate monohydrate), there are three methods.

One is to react with copper oxide and acetic acid. Take an appropriate amount of pure copper oxide, place it in a clean container, and slowly inject an appropriate amount of acetic acid solution. When the two meet, they react, just like a sling in a quiet lake, causing ripples. When the reaction is heated slightly, the reaction can be accelerated, just like a boat sailing downwind, accelerating the process. During this process, the copper oxide gradually fuses into acetic acid, and the two combine to produce copper acetate monohydrate. After the reaction is completed, the resulting solution is filtered to remove unreacted impurities, and then evaporated, concentrated, and cooled to crystallize, to obtain copper acetate monohydrate crystals.

The second is to react with copper carbonate and acetic acid. Select copper carbonate and slowly add it to acetic acid. When copper carbonate encounters acetic acid, it is like ice and snow meeting warm sun and gradually dissolves. This reaction is milder and does not need to be deliberately heated. However, appropriate warmth can also promote a smoother reaction. After the reaction is completed, the product is also precipitated through the steps of filtration, evaporation concentration, cooling and crystallization. This process needs to pay attention to the fine operation, just like carving beautiful jade, in order to obtain high-quality products.

The third is to react metallic copper with acetic acid and hydrogen peroxide. Take the copper sheet first, wash and dry it, put it in a solution containing acetic acid, and then slowly add hydrogen peroxide. At this time, hydrogen peroxide acts as a helpful agent to promote the reaction of copper and acetic acid. This reaction is like a clever cooperation. Under the impetus of hydrogen peroxide, copper is gradually converted into copper acetate. After the reaction is completed, copper acetate monohydrate is still obtained by filtration, evaporation concentration, cooling and crystallization. These three production methods have their own advantages and disadvantages. In actual operation, it is necessary to choose carefully according to factors such as the availability of raw materials, cost considerations, and product requirements.
