1. How did my silverware turn black? 2. Because the silverware sucks out the poison in your body. 3. In ancient times, silver needles were tested for poison. In the private sector, the statement that silverware can be tested is widely circulated. As early as in the Song Dynasty, the famous forensic scientist Song Ci's "Washing Collection" was used to record the autopsy of the silver needle, which was also cited as the standard for forensic examination at that time. 4. Today, there are still many people who have the idea that silverware can be tested for poison. Chopsticks are often used to check whether the food is poisonous. 5, true and false, if so, my body's toxins are too much. (Silver is especially black) 6. Is it true that the silver needle test is true? The ancients refer to the poison, mainly refers to the highly toxic arsenic, namely arsenic trioxide. The ancient production technology is backward, causing the arsenic to be accompanied by a small amount of sulfur and sulfide. The sulfide contained in it is in contact with the silverware, which can play a chemical role. To produce a layer of black "silver silver" on the surface of the silver needle. In modern times, the technology for producing arsenic has been much improved compared to ancient times. The refining is very pure, no longer accompanied by sulfur and sulfides. The metal of silver is chemically stable and does not react with arsenic under normal conditions. It can be seen that the ancients used silverware to verify the poison, which was limited by history and science. Some items are non-toxic, but they contain a lot of sulfur. When the silver needle is inserted, it will turn black. On the contrary, some are very toxic, but they do not contain sulfur, such as poisonous grass, nitrite, pesticide, poisonous rat, etc. Silver needles are in contact with them and there is no black reaction. Therefore, the silver needle can not identify the poison, and can not be used as a tool for testing. Although silver can not be tested, it can be disinfected. As long as it contains 50 millionth of milligrams of silver ions per liter of water, most of the bacteria in the water can be killed. The mechanism is: silver can form positively charged ions in water, can absorb bacteria in water, and gradually enter the bacteria. To cause the bacteria to lose their metabolic capacity and die. Therefore, it is still beneficial to use silver for bowls and chopsticks in daily life.

In the moment, people are increasingly favoring to wear silver jewelry. Silver jewelry is not only beautiful, but also economical and practical. The most important thing is that it will also benefit the human body. Compared with precious metals such as gold, it is more effective for human health. . How to "wash white" silverware?
