There are two chemical equations for copper making, the equation for copper to copper oxide

Concentrated sulfuric acid is first diluted to dilute sulfuric acid.

1) FE replaces Cu:

cuo + h2so4 === cuso4 + h2ofe + cuso4 === feso4 + cu2) h2 reduce cuo:

fe + h2so4 === feso4 + h2↑h2 + cuo === cu + h2o

1）cuo+h2so4=cuso4+h2ofe+cuso4=feso4+cu

2) CuO+Fe=Cu+FeO (Conditional High Temperature) The first is the famous wet refining Cu

The second utilizes Fe to be more reducible than Cu.

Concentrated sulfuric acid is diluted to dilute sulfuric acid.

Fe and dilute sulfuric acid to produce hydrogen.

Copper oxide is reduced with hydrogen at high temperatures.

Pre-made copper sulphate.

Replace copper with iron.

Copper is generated as a discriminated copper oxide.

The equation is: 2cu + o2 = heating = 2cuo. Copper is a metallic element and also a transition element.

Chemistry makes the blind symbol cu, English copper, atomic number 29. Pure copper is a soft metal, the surface is reddish-orange with metallic luster when it is first cut, and the elemental color is purple-red. Good ductility and high thermal and electrical conductivity.

Copper was one of the first metals used by humans. As early as prehistoric times, people began to mine open-pit copper mines, and used the copper obtained by carrying slips to make **, tools, and other utensils, and the use of copper had a negative impact on early human civilization.

The impact of the progress is far-reaching. Copper is a metal found in the earth's crust and oceans. The amount of copper in the earth's crust is about, and in individual copper deposits, the copper content can reach 3%-5%. Most of the copper in nature exists as a compound, that is, copper ore.

Copper heatedChemical equationsCu+O2 = (heated) Cuo. The resulting product can be referred to as a divalent copper salt. Divalent copper salts are the most common copper compounds, and their hydrated ions are often blue, while chlorine ligands are green, and are azurite and turquoise.

and other mineral colors, which have been widely used as pigments in history. Copper building structures can be corroded to produce patina (basic copper carbonate).

The decorative arts mainly used metallic copper and copper-containing pigments.

Uses of Copper:Copper is a non-ferrous metal that is very closely related to human beings, and is widely used in electrical, light industry, machinery manufacturing, construction industry, national defense industry and other fields, second only to aluminum in the consumption of non-ferrous metal materials in China. The copper ball is a red metal in a foot, and it is also a green metal.

It is said that it is a green metal, mainly because it has a low melting point and is easy to remelt and re-smelt, so it is quite cheap to use. In ancient times, it was mainly used for utensils, artworks and casting, and the more famous utensils and artworks such as the stepmother Shuding and the Four Sheep Fangzun.

High school biology tests proteins often add alkali to the protein, and then add copper sulfate solution, at this time the solution will turn purple, this reaction is called the biuret reaction. In the high school biological test of reducing sugar, copper sulfate and sodium hydroxide were used to make Feilin reagent, and the reducing sugar was formed by boiling water bath to form a brick-red precipitate.

Application field: Inorganic industry is used to manufacture other feed salts such as cuprous chloride, copper chloride, copper pyrophosphate, cuprous oxide, copper acetate, copper carbonate, etc. The dyes and pigments industry is used to manufacture copper-containing monoazo dyes such as reactive brilliant blue, reactive violet, etc. It is used in the organic industry as a catalyst for the synthesis of fragrance and dye intermediates, and as a polymerization inhibitor for methyl methacrylate.

In the paint industry, it is used as a biocide in the production of antifouling paint for ship bottoms. In the electroplating industry, it is used as a main salt for all-bright acid copper plating and a copper ion additive. In the printing and dyeing industry, it is used as an oxygen aid for mordants and fine dyed fabrics.
