Does copper sulfide react with sulfuric acid?

Copper sulfide reacts with sulfuric acid only because copper sulfide does not ionize, so even if there are hydrogen ions in the solution, it will not react to form hydrogen sulfide, but it will dissolve in concentrated sulfuric acid and undergo an oxidation-reduction reaction; therefore, copper sulfide reacts with sulfuric acid.

Copper sulfide is an inorganic compound, the chemical formula is CuS or CuI2CuII(S2)S, so in fact, two-thirds of the sulfur is persulfide ions, and two-thirds of the copper is cuprous ions, which is dark brown and extremely Insoluble, is one of the most insoluble substances (second only to silver sulfide, mercury sulfide, palladium sulfide and platinum sulfide, etc.), because its insoluble nature allows some seemingly impossible reactions to occur.

Overview of copper sulfide CuS powder

Copper sulfide CuS powder is an inorganic compound with a chemical formula of CuS, so it is actually a mixture of cuprous sulfide and supersulfide. It is a black and brown amorphous powder or granular substance. It is extremely difficult to dissolve and is one of the most difficult to dissolve substances, because its insolubility makes certain seemingly impossible reactions occur. The bonding in copper sulfide cannot be accurately described by a simple oxidation state, because the nature of the Cu-S bond is to some extent covalent rather than ionic, and has a high degree of delocalization, resulting in complex electronic energy bands structure.

Copper sulfide CuS powder is a compound and mineral, which can be divided into three categories: monosulfide, disulfide and mixed monosulfide. Copper sulfide CuS powder is a naturally occurring natural mineral called copper ketone. It is carried out in moderation. Both synthetic materials and minerals contain copper sulfide.

Copper sulfide is a series of compounds and minerals that constitute minerals and synthetic materials. Some copper sulfide is an economically important ore. The main minerals of copper sulfide are Cu2S (chalcopyrite) and CuS (copper porphyry). In the mining industry, limonite or chalcopyrite consisting of a mixture of copper and iron sulfide is often referred to as "copper sulfide." Chemically, "binary copper sulfide" is any binary compound of elemental copper and sulfur. Regardless of its source, the composition of copper sulfide varies greatly at 0.5 Cu / S2 and includes many non-stoichiometric compounds.

Application of copper sulfide CuS powder

Copper sulfide CuS powder is used as a textile mordant, agricultural pesticide, water fungicide, feed additive and copper plating. Solar cells, super-ion conductors, photodetector conductive electrodes, photothermal spectrum analysis conversion equipment, microwave shielding coating radio wave absorbers, infrared radiation polarizers for gas sensors.

The aqueous solution of ketone sulfate has a strong bactericidal effect. Mainly used in agriculture to prevent and control many diseases such as fruit trees, malt, potatoes, rice and so on.

Good effect, but poor effect on rust and powdery mildew. At the same time, it causes phytotoxicity to plants,

At the same time, it is only used for crops with strong tolerance to copper ions or fruit trees in the dormant period. It is a preventive bactericide and needs to be used before the onset of disease.

Copper sulfide CuS powder can also be used to remove algae in rice fields and ponds. It is also a kind of trace element fertilizer, which can improve the stability of chlorophyll and prevent premature destruction of chlorophyll.

Promote crop absorption. When crops lack copper, they lose their green color. The fruit tree lacks copper, the fruit is small, and the flesh becomes hard. In severe cases, the fruit tree will die. Crops that are sensitive to copper are cereal crops, such as wheat, barley, and oats.

Copper sulfide CuS powder is mainly used for seed treatment and extra-root topdressing.

Copper and copper alloys are widely used in electronics, machinery, national defense and other fields due to their excellent physical and mechanical properties, and play an important role in the development of national economy and science and technology. Copper sulfide minerals are the main mineral resources for extracting copper, which account for percent 80 of the copper ore resources. Therefore, the theoretical and experimental research on copper sulfide minerals has attracted widespread attention. Copper sulfide minerals mainly include chalcopyrite, chalcocite, copper blue and bornite. Among them, chalcocite has the strongest effect on xanthate, followed by copper blue, then bornite, and yellow Copper mine. Because a kind of copper sulfide ore often contains several different copper sulfide minerals, the flotation conditions such as the type, dosage, pH and other reagents required for the flotation of various copper sulfide minerals are also different. In addition, the difficulty of oxidation of different copper sulfide minerals is also different. Among them, chalcocite is the easiest to oxidize. When the copper ore contains chalcocite, the oxidation will cause a large amount of copper ions in the slurry. , The separation of copper and sulfur caused great trouble. The flotation behavior of minerals depends on the nature of the mineral, and the nature of the mineral depends on the electronic structure of the mineral. Different copper sulfide minerals have different chemical compositions, crystal structures and electrochemical properties. For example, chalcocite contains the highest copper content, reaching percent 79.86, while chalcopyrite contains the lowest copper content, only percent 34.56; in addition, Common chalcopyrite belongs to the tetragonal crystal system, chalcopyrite belongs to the hexagonal crystal system, and copper blue has a complex layered structure; in terms of conductivity, chalcopyrite belongs to semiconductors, while chalcopyrite and copper blue are conductor. Therefore, studying the electronic structure of copper sulfide minerals is of great significance for understanding the difference in flotability of different copper sulfide minerals in essence.
