Silver can become discolored due to tarnishing, which is caused by a chemical reaction between silver and sulfur-containing substances in the air, such as hydrogen sulfide. Other factors like exposure to moisture, certain foods, and cosmetics can also contribute to silver tarnishing. Regular cleaning and proper storage can help prevent and remove discoloration.

Pure silver can tarnish but not as easily as Sterling Silver.
Silver turns yellow due to a chemical reaction with sulfur compounds in the air or on the skin, forming silver sulfide. This tarnishing process causes the silver to lose its shiny appearance and take on a yellowish hue.
Silver oxide can be reduced to silver metal by heating it in the presence of a reducing agent, such as hydrogen gas or a metal like aluminum or zinc. The high temperature causes the oxygen in the silver oxide to be removed, leaving behind elemental silver.
Yes, silver tarnishing is a chemical change that occurs when silver reacts with sulfur compounds in the air to form silver sulfide. This reaction causes the silver to darken or develop a patina over time.
No it does not loose its color
discolour
There are many causes. The most common ones are due to eating food, coffee, tea, wine, soft drinks and smoking. As teeth are naturally porous, molecules can enter the teeth and discolour them. Our teeth naturally discolour with time during the course of our lives. Even so-called naturally yellow teeth can be whitened.For more information visit: http://www.dentstore.co.uk
It is a metallic surface that will not discolour or stain, especially be oxidisation
With tissue paper, else it will discolour
YES.It will turn your white wall into black.
The juices in the apple react with the oxygen in the air, causing the flesh to discolour.
It causes corrosion
Metallic silver
Sterling silver tarnishes because when silver is exposed the air it causes chemical reactions and creates Silver Nitrate. This is what will leave black marks on your skin when you wear something made of silver.
It's called oxidation. Rust if it were on steel. Oxygen in the air combines with the silver and causes it to darken.
