5 thoughts on “What is the reason why gold turns white”
Krystal
Gold is exposed to substances containing HG elements, a chemical reaction occurs, and a white golden mercury compound is produced. In wearing gold jewelry, mercury or mercury types are exposed to the process of germination, and the colors are changed by chemical reactions, and mercury or mercury substances mostly exist in washing products, cosmetics and skin care products. But after high temperature, it will be restored to golden yellow. If people have golden platinum rings on the adjacent fingers, the fingers often move, causing the rubbing of gold and platinum to rub each other. For such a white gold jewelry, you can rub the canvas hard to restore the golden to the light; similar to this, some cosmetics or hair dye contains trace lead, and the gold will turn black when it encounters the lead capacity. Extension information: one of the gold is one of the rare, precious and extremely valued metals. Internationally, gold is generally based on ounces. In ancient China, "two" was used as a gold unit, and it was a very important metal. It is not only a special currency for reserves and investment, but also an important material for the jewelry, electronics, modern communications, aerospace and air industry and other departments. The steam emitted when the gold is melted is green; its gold powder is usually brown during the smelting process; if it is cast into a thin piece, it can also transmit green light. The color of gold is golden yellow, metal luster, difficult to break down. The hardness is 2-3, the pure gold is 19.3, and the melting point is 1064.4 ° C; it has good ductility and can be pressed into thin foil. It has extremely high heat transfer and conductivity. The resistance of pure gold is 2.4P. Pure gold has good anti -chemical corrosion and is the best electroplating material. Gold, as a precious metal, has good physical characteristics. "Real Gold is not afraid of fire" is that the chemical stability of gold is very high. It is not easy to chemically react with other materials. You don't have to worry about oxidation and discoloration. Even in the melting state, it will not be oxidized and discolored. The density is strong and the feel is heavy. Good toughness and ductility, good guidance. It pure gold has gorgeous yellow, but the color changes greater after mixed with other metals. For example, the gold and copper alloy are dark red, and the silver alloy is light yellow or gray -white. Jin Yi was grinded into powder, which is why Jin is scattered in nature. Pure gold jewelry is also easily worn and reduced.

The cause of gold is as follows: The gold is impure, and the oxidation of impurities makes gold white. This and other metals (such as silver) are placed together for a long time, causing the surface diffusion between the metal and causing the surface to turn white. Gold (English GOLD), commonly known as gold, chemical element symbols AU, gold code xauusd is a yellow -luster metal. Gold has good physical attributes, stable chemical properties, high ductility and scarce quantity. It is not only for special currency for reserves and investment, but also the jewelry, electronics industry, modern communication, aerospace and other departments and other departments Important materials. Gold is the gold of the chemical symbol as AU. Gold is one of the rare and most precious metals in the world. Gold is the earlier metal discovered and utilized by humans. Because of its scarcity, special and precious, it has been regarded as the first of hardware since ancient times, and has the title of "King of Metals".
There are often customers who take their own gold jewelry to consult: Why does their jewelry suddenly change color, and there are some white spots on the jewelry. Is it fake? In fact, these concerns are superfluous. As long as they are bought in a regular gold shop, in general, the quality is guaranteed. Customers' jewelry is slightly cleaned by the maintenance personnel, and the white spots will disappear. Gold jewelry is as bright as new. What is this? Gold is one of the most stable metals in nature. It does not respond to various oxide gas in the air at normal temperature. It does not respond to triple major acid (sulfuric acid, nitric acid, hydrochloric acid) and weak acid. ) Can corrode it. However, brine tofu, one object is reduced, liquid metal mercury (mercury) is easy to combine with gold to generate a compound called gold mercury, as white, so as long as gold jewelry contacts mercury, it will immediately change immediately Bai, because mercury is volatile, even if it is far away, it can cause color change. Most of these situations occur in hospitals or clinics, and most of them are caused by a thermometer that causes mercury leaks.
Gold is impossible to turn white. If it will turn white, you should consider the quality of the product. Normally, if you do n’t wear gold, you can only become lighter.
