Can the silver comb brought back from Yunnan tourism soak in water?

The physical properties of silver are stable, and simply soaking in water will not cause silver to dissolve.

Silver is a beautiful silvery white metal with good ductility, and its electrical conductivity and thermal conductivity are the highest among all metals. Silver is often used to manufacture highly sensitive physical instruments and components, various automation devices, rockets, submarines, computers, nuclear devices and communication systems. A large number of contacts in all these devices are made of silver.

Silver is also a metal that can be eaten by human beings. In China and India, there are records of wrapping food with silver foil and taking pills.

Silver ions and compounds are toxic to some bacteria, viruses, algae and fungi, but almost harmless to human body. This bactericidal effect of silver enables it to kill living things in vitro. However, it is very difficult to test and standardize silver products.

Silver is added in large quantities to gels and bandages. The antibacterial property of silver comes from silver ions. Because silver ions can form strong bonds with substances used by some microorganisms to breathe (such as some molecules containing oxygen, sulfur and nitrogen), these substances can not be used by microorganisms, which leads to suffocation and death of microorganisms.

Before the invention of antibiotics, during World War I, silver-related compounds were used to prevent infection. ..
