Can silverware really be tested?

The ancients referred to the poison, mainly refers to the highly toxic arsenic, namely arsenic trioxide. The ancient production technology was backward, causing a small amount of sulfur and sulfide in the arsenic. When the sulfur contained in it is in contact with silver, it can react chemically to form a black "silver sulfide" on the surface of the silver needle. In modern times, the technology for producing arsenic is much more advanced than ancient times, and the refining is very pure. Participate in sulfur and sulfides. Silver metal is chemically stable and does not react with arsenic under normal conditions. It can be seen that the ancients used silverware to test poisoning because of historical and scientific limitations.

Some items are not toxic, but they contain a lot of sulphur, such as egg yolk. When the silver needle is inserted, it will turn black. On the contrary, some are very toxic substances, but they do not contain sulfur, such as poisonous cockroaches, nitrites, pesticides, poisonous rodenticides, cyanide, 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 one million milligrams of silver ions per liter of water, most of the bacteria in the water can be killed.

The principle of silverware poisoning is that silver can form positively charged ions in water, can absorb bacteria in water, and gradually enter the bacteria, so that its catalyst-è„¢ system is closed and inactivated, and the bacteria lose their metabolic capacity and die. . Therefore, it is still very beneficial to use silver as a bowl and chopsticks for daily life. Silver can only detect some poisons containing sulfur, and organic poisons cannot be detected. If you go to the wild, wash the rice, wash the silver jewelry, chopsticks, rings, etc. and put them there to stir them to kill a lot of microorganisms inside.
