Question

Give reason:
Silver articles when exposed to air gradually turn blackish.

Answer 1

Silver is a chemical element with the atomic number 47 and the symbol Ag. It is a lustrous, soft, white transition metal with the highest electrical conductivity, thermal conductivity, and reflectivity of any metal.

Complete answer:
When silver is exposed to sunlight, it eventually becomes black because the silver metal reacts with the sulphur in the air to form a film of silver sulphide, which is black in colour.
Silver reacts with sulphur compounds in the air, such as hydrogen sulphide (H2S), and becomes black when exposed to it. Corrosion is the term for the phenomenon, and tarnishing is the term for silver tarnishing. Silver sulphide is the black material that forms.
Aside from that, the natural oils produced by your skin can react with your silver jewellery. The amount of silver that interacts with these substances from your skin is highly dependent on the foods you eat, the amount of alcohol you consume, and whether or not you are taking medication.
These factors affect the skin's acidity, which can trigger a reaction. Sweat (which contains ammonia) also increases the acidity of the skin, which could tarnish the silver.

Note:
There are some steps you can take to improve the situation.
-Silver jewellery should not be kept in humid areas such as the bathroom or the kitchen.
-After you've applied make-up, perfume, hair spray, and other beauty items, put on your silver jewellery.
-When going swimming, cleaning (cleaning items are really bad), hand washing, or coming into contact with sea water (salt water), remove your silver jewellery.
