Almost all the things of our daily life are connected to Science. If we start to understand this science then our understanding and knowledge both grow. This is also an example of one such incident.
Silver Sulphide and Hydrogen gas are formed by reaction of Silver with Hydrogen present in the air. This Silver Sulphide gets deposited over the pots. The color of Silver Sulphide is black which appears to be deposited over silver.
Corrosion: Corrosion is a natural process in which a metal is converted into a more chemically-stable form, such as its oxide, hydroxide, or sulfide. It is the gradual destruction of materials (usually metals) by chemical and/or electrochemical reaction with their environment.
