Question

Explain the process of corrosion of silver

Answer 1

Dear Student
Corrosion is the process in which metals get deteriorated by action of air, moisture, chemicals etc.

Corrosion causes damage to metal surface.

Corrosion of silver causes blackening of silver objects in exposure to atmosphere. Silver reacts with hydrogen sulphide present in the air to form a layer of silver sulphide which is black in colour.
Equation:
2Ag + H₂S→Ag₂S + H_{​​​​​​2}
