Silver Hydrogen Sulfide Reaction
Silver reacts with hydrogen sulfide
There are silverware in the world. When exposed to air containing hydrogen sulfide, the color changes for a long time. This is because of the reaction between silver and hydrogen sulfide.
At the beginning, silver is pure and beautiful, shining brightly. When encountering hydrogen sulfide, it gradually changes. Cover the gas of hydrogen sulfide, and the molecules are active. When it encounters silver, sulfur atoms combine with silver atoms.
The atomic structure of silver, the outer electrons are easy to move. In hydrogen sulfide, sulfur has the property of stealing electrons. When the two meet, sulfur lures the electrons of silver, and then forms silver sulfide.
Silver sulfide, black in color. At the beginning, it changes slightly, and the color gradually darkens; after a long time, black stains cover the surface of the silverware. Looking at it, it is no longer as bright as it used to be.
Although the ancients did not understand the principle of chemistry, they also knew that silverware became dark, which was related to the surrounding gas. Or hide it in a secret place, or wipe it often, hoping to maintain its luster.
Today, science is prosperous, and we know the mechanism of the reaction between silver and hydrogen sulfide. According to this reason, the method of anti-oxidation can be used to protect the beauty of silverware, so that it will last forever in the world.
