How to go to turquoise

1. The following methods can be used to remove copper green: cleaning agents: prepare some cleaning agents, such as acetic acid, lemon juice, salt and baking soda. Pour the cleaning agent into the container, soak the copper products in the cleaning agent, the soaking time depends on the degree of copper green, generally need to soak for 30 minutes to 1 hour.

2. Vinegar soaking method: wash the copper, place it in a small plate, and pour in a little edible vinegar until immersed. After 24 hours, remove the rust with a small brush, then wash the vinegar with clean water and wipe it off. Soak in boiling water: first put the copper into a bowl, and then pour in boiling water at a temperature of 80 ℃ to 90 ℃ until it is submerged.

3. Use vinegar to remove green rust: soak the cloth in vinegar, then add appropriate amount of salt or cuttlefish bone powder to wipe, which can effectively remove copper green. Removal of copper green by mechanical friction: although it can be removed by mechanical friction, this method is time-consuming and may cause damage to the surface of copper ware.

4. Vinegar soaking method: dip in vinegar with cloth, then wipe with appropriate amount of salt or cuttlefish bone powder, and the green rust can be removed. Mechanical friction: remove the copper green by mechanical friction, but this is not only troublesome, but also damages the surface of the bronze ware.

Chemical equation of copper green

1. The chemical formula of turquoise is Cu (OH) CO. Molecular weight: 22076, appearance: malachite green fine amorphous powder basic copper carbonate (copper green), malachite green color, so also known as malachite, is a valuable mineral gem.

2. Cu (C2H3O2) 2 ·H2O. According to the public information related to the query, the chemical formula of turquoise is Cu (C2H3O2) 2 ·H2O. Cu represents copper, C2H3O2 represents acetic acid ion, and H2O represents water molecule.

3. The chemical equation of turquoise is 2Cu+O2+CO2+H2O=Cu2 (OH) 2CO3. The related knowledge is as follows: copper green, also known as basic copper carbonate, is a common copper corrosion product. When copper comes into contact with moist air, it reacts with oxygen, carbon dioxide and water to form basic copper carbonate.

4. The chemical formula of turquoise is Cu2 (OH) 2CO3, also known as malachite (the main component is Cu2 (OH) 2CO3, impure). It is a kind of precious mineral gem, which belongs to basic carbonate and is a kind of salt. It is a substance produced by the reaction of copper with oxygen, carbon dioxide and water in the air, also known as copper rust (copper green).

5. The formation of Cu2 (OH) 2CO3 from copper in moist air is the result of the interaction of copper with water, oxygen and carbon dioxide in the air. So the answer is: 2Cu+CO2+O2+H2O ═ Cu2 (OH) 2CO3, short for bronze ware, also known as all kinds of bronze ware.

6. The chemical formula of turquoise is Cu2 (OH) 2CO3, which is called basic copper carbonate, and the chemical equation for the formation of copper green is 2Cu+O2+CO2+H2O=Cu2 (OH) 2CO3.

Ask for advice on the production of copper green

1. Hello, your question, how to make copper coins produce copper green? Generally speaking, the chemical method is that copper sulfate and sodium bicarbonate will form turquoise after a period of time. I hope I can help you.

2. The chemical equation of turquoise is 2Cu+O2+CO2+H2O=Cu2 (OH) 2CO3. The related knowledge is as follows: copper green, also known as basic copper carbonate, is a common copper corrosion product. When copper comes into contact with moist air, it reacts with oxygen, carbon dioxide and water to form basic copper carbonate.

3. Cu2 (OH) 2CO3 is produced by the reaction of copper with O _ 2 Permian CO _ 2 ·H _ 2O in air. CuO,CO2,H2O can be generated by heating.

4. The identification of true and false coins mainly depends on the production technology, grain, weight and glossiness, etc., the pattern of counterfeit coins is relatively rough, and it will blacken over a long time, and there is no real coin with luster. Copper utensils will rust after being kept in water for a long time, that is, copper rust, commonly known as copper green.

5. The chemical structure of these copper greens is a mixture of basic copper sulfate and basic copper carbonate. Now in order to restore the ancient heritage, architectural decoration, arts and crafts to create an antique appearance, it is necessary to study the method of rapid formation of malachite green.

6. Copper will form turquoise when oxidized at room temperature, which is green for basic copper carbonate; copper oxide will be formed when heated and oxidized, which is black; cuprous oxide may also be oxidized to cuprous oxide, which is brick red.

Bronze wares are easy to turn green after a long time. What is the reason for this?

1. In the production process, due to the needs of the process, for the copper parts that have just been processed or polished, if the surface anti-oxidation protection treatment is not done in time, the brass parts will be oxidized and discolored, and rust will occur on the surface for a few hours or three or five days.

2. Copper turns green after oxidation in the air, which is because copper reacts with oxygen to form turquoise. Turquoise is a turquoise compound whose chemical formula is Cu2O. Turquoise is an unstable compound that continues to oxidize in the air and eventually turns into reddish-brown copper oxide.

3. The greenness is normal, and the oxidation reaction of copper is easy to occur in cellar for many years, especially the phenomenon of bronze coins. Relatively speaking, brass coins are corrosion-resistant and anti-aging, and coins with high tin content are not suitable for aging.

4. However, the reason why copper turns green is that copper reacts with water, carbon dioxide and oxygen in the air to form a green compound, referred to as copper green. It is often attached to the surface of the bronze ware, so it looks like the surface of the bronze ware has turned green.

5. Copper reacts with water, carbon dioxide and oxygen in the air. The reason why copper hair is green is that copper reacts with water, carbon dioxide and oxygen in the air to form a green compound, referred to as copper green. From the bronze ware green rust, mainly depends on the environment, under the wet chemical erosion, the bronze ware can form a thick green rust in one year.

Does anyone know an easy way to turn copper into copper rust quickly?

Copper is also oxidized, its color is green, and at this time it becomes turquoise.

Sulfuric acid, nitric acid and sodium carbonate. The main component of copper rust is basic copper carbonate. Copper sulfate can be quickly prepared from the mixture of copper, sulfuric acid and nitric acid. Copper sulfate and sodium carbonate can quickly produce basic copper carbonate, that is, copper rust.

"transplant rust": transplant or inlay the ancient rust on the bronze ware to the surface of the imitation, and then use the various methods mentioned above to rust. I assure you, these methods can be seen at a glance. The shape, craftsmanship, distribution and degree of corrosion of your bronze ware are all easy to reveal.

How to make copper rust quickly: put in a wet environment, the chemical equation of copper rust is: 2Cu+O2+H2O+CO2=Cu2 (OH) 2CO3 so copper rust needs oxygen, water, carbon dioxide, in wet places it is easy to make copper rust.

Pour water on the brass surface and add a small amount of salt. Salt and water form electrolyte solution, which makes the primary battery corroded by absorbing oxygen and accelerates the corrosion rate of brass.

Put it in moist air rich in carbon dioxide. Or smear a large amount of NaOH copper to form turquoise is a very slow process. I guess your purpose is just to identify copper products. You can think of another way.
