What do you do if the silver is oxidized? Is silver prone to oxidation

Ten Methods of Silver Jewelry Cleaning:

1. Use Coca-Cola soaking, soaking time is 12 hours.

2. Adopt the method of applying lipstick to the cloth, then wiping the silverware, and finally rinsing with water.

3. Use acetic acid to scrub.

4. Use overnight tea steeping.

5. Use a silver cloth to wipe.

6. Soak in silver washing water for one to two minutes.

7. Use the correction liquid to coat the silver jewelry, and wipe the silver jewelry with a cloth before the correction liquid is dry.

8. Use toothpaste and toothbrush to scrub.

9. Use a lighter to burn black silver jewelry (Note: This method is only limited to plain silver (gold-filled and inlaid silver jewelry cannot be used.) The temperature should not be too high, and it is forbidden to use matches, because matches contain sulfur, which will turn the silver ornament into silver sulfide) and then polish the silver ornament with a silver cloth.

This method makes plain silver jewelry particularly bright.

10. Silver jewelry with plain silver is often blackened, although it can be cleaned frequently, but it is also very troublesome. I teach you to prepare a bottle of clear nail polish before cleaning your silver jewelry, blow dry it with a hair dryer after cleaning, and then apply a layer of nail polish to the clean silver jewelry. My customers have tried this method to keep their silver jewelry for up to a year without blackening.

Where did you buy it from, and where do you go back?

That's usually free of charge.

Or find a random jewelry store and give him some money.

<> silver is easy to oxidize, silver oxidation is mainly due to the reaction with oxygen and water in the air to produce silver oxide, silver oxidation will become gray-black. Silver also reacts with sulfur in the air to produce silver sulfide, which turns into a shiny, deep black. Silver jewelry should avoid contact with chemicals such as perfume, and should not be worn with cinnabar jewelry.

Silver is a very reactive metal, so it can easily oxidize with water and oxygen in the air to produce silver oxide, which causes the silver to turn grayish-black. After the silver is oxidized, it can be soaked in Coca-Cola for 12 hours, and finally rinsed with water and wiped dry.

Silver also reacts with sulfur in the air to produce silver sulfide, which turns into a shiny deep black. If it is vulcanized, it can be steeped with overnight tea or brushed with a professional silver wash and toothpaste.

Silver jewelry should avoid contact with perfume, dish soap, shower gel and other chemicals to prevent silver from reacting. Silver cannot be worn with cinnabar jewelry because the main ingredient of cinnabar jewelry is mercury sulfide, and the sulfur in it reacts with silver.

1.What is Silver Oxidation?

Silver oxidation is the product of the reaction of silver (Ag) and oxygen (O) with the chemical formula Ag2O. Silver oxide is an important chemical reagent with a wide range of applications in medicine, metallurgy, electronics and other fields. However, during use, silver oxides may produce contaminants that threaten human health and environmental safety, such as heavy metal ions and organic matter.

2.Treatment method after silver oxidation.

The treatment methods after silver oxidation include physical methods and chemical methods. Commonly used physical methods include filtration, precipitation, centrifugation, and adsorption; Chemical methods include reduction, oxidation, displacement, and heating.

3.The physical method deals with silver oxidation.

Filtration. The solution containing silver oxide is filtered through filter paper or other suitable filter material to separate the solid from the solution.

Precipitation. Chemical reagents (such as sodium chloride, sodium hydroxide, etc.) are used to form a solid precipitate of silver oxide, and the precipitate is separated and processed by filtration or centrifugation.

Centrifugal. The silver oxide-containing solution and the precipitate after the reaction of the reagent are separated by a centrifuge, and the precipitate is treated by other methods.

Adsorption. The silver ions in the solution are adsorbed with adsorbents (such as activated carbon, quicklime, etc.), and then the adsorbents are treated.

4.Chemically treated with silver oxidation.

Restore. The silver oxide is reduced to silver ions, and then the silver ions are treated by other methods. Commonly used reducing agents are sodium sulfite, sodium thiosulfate, etc.

Oxidation. The solution containing silver oxide is oxidized in an oxidant (such as hydrogen peroxide, potassium permanganate, etc.), and the product is dismantled after oxidation for treatment.

Replacement. A solution containing silver oxides is reacted with a chemical reagent to convert the silver ions into other ions, and the ions are treated by other methods.

Heating. The solution containing silver oxide is heated to decompose the silver oxide to obtain metallic silver or other products, and then the product is treated by other methods.

5.Environmental significance of silver oxidation.

Silver oxide is a harmful substance, which is harmful to the environment and human health. Treating silver oxides not only reduces environmental pollution, but also saves resources and reduces costs.

6.Conclusion.

Treating silver oxides is an environmentally friendly, healthy and sustainable choice. When selecting treatment methods, different physical and chemical methods should be selected according to the specific situation to ensure effective, safe and feasible treatment results.

1. Silver washing water cleaning method: generally the oxidation is too serious, or the gap is complex and the shape is complex, the most suitable choice of silver washing water, put the silver jewelry that needs to be treated into it, soak it for 3 seconds, take it out, rinse it with water immediately, and then dry it with a paper towel and save it.

2. Cleaning method of polishing strip: choose the number of ultra-fine polishing strips, don't choose the kind with thick surface, remove oxidation is very fast and wipe it directly, and the brightness is greatly improved after polishing, and it can be up to several months without oxidation.

3. Cleaning method of wiping silver cloth: daily silver jewelry that is slightly yellowed and blackened can be wiped several times with a silver cloth, which can generally restore the original gloss. It should be noted here that the silver cloth should not be cleaned no matter how many times it has been used.

1. Cleaning method of silver washing water.

Generally, the oxidation is too serious, or the gap is complex and the shape is complex, it is most suitable to choose silver washing water, put the silver jewelry that needs to be treated into it, soak it for 3 seconds and take it out, immediately rinse it with water, and then dry it with a paper towel and save it.

2. Cleaning method of polishing strip.

The polishing strip selects the number of ultra-fine numbers, don't choose the kind with a rough surface, the removal of oxidation is very fast and directly wiped on it, and the brightness is greatly improved after polishing, and it can be up to several months without oxidation.

Silver oxidation can be cleaned with a silver cloth, silver wash and toothpaste.

The easiest way is to use a professional silver cloth to wipe the surface of the silver jewelry, and it will soon restore the luster of the dry town. Clean with professional silver washing water, the method is very simple, but if it is not handled well, it will also damage the silver jewelry, the most important thing in this method is to control the soaking time, generally no more than 3 seconds, and the time can be slightly shortened and extended according to the specific situation.

Clean with toothpaste and a soft brush, but be careful not to use toothpaste with frosted particles, which will damage the surface of the silver.

Care of silver jewelry:

Do not wear other *** jewelry at the same time when wearing sterling silver jewelry to avoid collision deformation or abrasion. Even if it is not loaded at the same time, after a long time, the silver jewelry will still oxidize and change color, whether it is electroplating or no coarse plating.

Therefore, friends who love silver jewelry must learn how to maintain sterling silver and prolong the light time. Avoid contact with water vapor and chemicals in sterling silver jewelry, avoid swimming, especially going to the sea, wipe it with a cotton cloth after wearing sterling silver jewelry every day, and put it in a jewelry box or bag to seal and preserve. <>
