Can I take a bath with silver jewelry?
Silver ornaments can be dyed with water. Pure water will not react with silver, but seawater or other chemicals will react easily. Therefore, in complex water environment, it is best not to use silver bracelets.
Silver is an unstable element, which easily reacts with sulfur, leading to blackening. Human sweat contains a lot of sulfur, which will work when it comes into contact with silver ornaments.
Moreover, if people are in some polluted environments and there are many compounds such as acid gas, hydrogen sulfide and nitric oxide in the air, the silver ornaments will turn black. Furthermore, the discoloration of silver ornaments may also be caused by a serious shortage of ingredients. Even if the above situation is ruled out, under normal circumstances, the surface of silver jewelry will be oxidized and the color will become dull after being worn for about half a year.

Precautions for wearing silver ornaments:
Silver absorbs mercury easily. After absorbing mercury, the surface quality is seriously damaged and completely tarnished, forming amalgam (also known as mercury silver). In humid air, silver is easily corroded by sulfur vapor and hydrogen sulfide, which makes the surface black (which is one of the basic conditions for the formation of white iron ore). To this end, we should pay attention to the following matters in our daily life:
1, cosmetics contain not only mercury, but also sulfur, which can make silver into black silver sulfide. In addition, if the air contains sulfur, it is not suitable to wear silver.
2. Ozone can also cause silver to turn black. For example, negative ion generators and disinfection cabinets used in daily life are not suitable for placing silver ornaments.
3. Some egg birds will produce hydrogen sulfide gas after deterioration.
The purification of tap water often contains bleaching powder or chlorine, which has a serious corrosive effect on silver. After erosion, silver loses its luster and produces white silver chloride. Therefore, it is not advisable to wear silver in the bath.
5. Washing powder contains bleach, and the main component of bleach is chlorine, which has a certain corrosive effect on silver.
6, mercury (mercury) and silver will play a role, serious damage will occur, and even the formation of mercury paste, so be careful when using the thermometer.
7. Silver is soluble in hydrochloric acid and nitric acid.
