Why do silver articles turn black when kept in the open for few days?
Silver exposed to the air will combine with the Oxygen in the air to form Black Silver Oxide.This is especially true of the purer samples of Silver like Sterling Silver and purer.
Is a silver knife and fork tarnish when they are exposed to air for several weeks a chemical or physical change?
The tarnishing of silver when exposed to air for several weeks is a chemical change. This is because the silver reacts with sulfur compounds present in the air to form silver sulfide, which creates the tarnished appearance on the surface of the utensils.
Why do silver articles become black after some time when exposed to air?
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.

What happens to sliver when exposed to oxygen?
When silver is exposed to oxygen, it can undergo a chemical reaction and form a layer of silver oxide on its surface. This can cause the silver to tarnish, leading to a darkening or discoloration of the metal. Regular polishing can help remove this oxidation layer and restore the shine of the silver.
