Why does the silver darken on the body?

Many women, like many men lovebeautiful and not very (all have different taste) jewelry. Each piece of jewelry requires special care for it. This is to ensure that it does not lose its beauty and brilliance. We often come across the fact that some silverware lose its whiteness and darkens. What is the reason for this? Let's try to figure out why the silver on the body darkens.

Darkens silver: causes

It should be noted that silver has a habit of darkening not only on the human body, but also in remoteness from it. Consider chemical reactions that lead to a darkening of silver on the human body.

The main culprit is that the silver productloses its shine is the sweat of a person. The more sweat is released, the faster the oxidation of silver. Oxidation, respectively, leads to its darkening. This process is not accidental. The sweat, which emits a person, contains hydrogen sulphide. The main factor of the rate of oxidation is the amount of hydrogen sulphide in the pot. The more it is, the faster the reaction, and the faster the silver product darkens.

That's what happens to silver, whichis contained in humidified air. Under the influence of the smallest particles of bivalent sulfur contained in moist air, a deposit of sparingly soluble silver sulphide is formed. This coating also causes the darkening of silver. It quickly acquires a brown color, and then the silver product completely blackens.

We remind you that in order to preserve the gloss and purity of ornaments, do not forget to clean the silver as it darkens.
