Silver articles turn black over time when exposed to air due to a chemical reaction with sulfur in the environment, forming silver sulfide. This is known as tarnishing. It can also be accelerated by factors like humidity and exposure to certain chemicals. Regular cleaning and storage in airtight containers can help prevent tarnishing.

Silver turns black due to a sulfur reaction in the metal, and it happens more quickly in human sin. The purity of Silver can be determined by how soon it tarnishes.

Why do silver articles turn black when kept in the open for few days?

Silver articles turn black when exposed to air because they react with sulfur compounds present in the air to form silver sulfide, which is black in color. This process is known as tarnishing and is a natural reaction of silver with air. Regular cleaning and storage in airtight containers can help prevent tarnishing.


Why do silver articles turn black when kept in the open for few days and what is the name of black substance formed?

Silver articles turn black when exposed to air due to a chemical reaction with sulfur compounds in the air, forming silver sulfide. This black substance formed is called tarnish, which is a layer of silver sulfide that can be removed by polishing.


Does silver get rusty?

Silver does not rust in the same way that iron does. However, silver can tarnish when exposed to sulfur or other chemicals in the environment, causing a darkening or dulling of the surface. This tarnish can be easily removed with silver polish or other cleaning methods.


Does silver turn black in bleach?

Yes, silver can turn black when exposed to bleach due to a chemical reaction with sulfides present in the environment. This black tarnish can be removed using appropriate silver polish or cleaning methods.


What type of reaction takes place when silver bromide is exposed to sunlight?

Photodecomposition reaction occurs when silver bromide is exposed to sunlight. The sunlight causes the silver bromide to decompose into silver and bromine atoms, leading to a color change from white to grey or black.

What happens when silver nitrate exposed to light?

Silver nitrate is photosensitive, meaning it decomposes when exposed to light. This decomposition results in the formation of elemental silver and nitrogen dioxide gas. This reaction can be used to create photographic films and papers.
