Question

define corrosion. why do copper vessels turn green with passage of time?​

Answer 1

Explanation:

Corrosion is when a refined metal is naturally converted to a more stable form such as its oxide, hydroxide or sulphide state this leads to deterioration of the material.

Copper turns green because of chemical reactions with the elements just as iron that is left unprotected in open air will corrode and form a flaky orange-red outer layer, copper that is exposed to the elements undergoes a series of chemical reactions that give the shiny metal a pale green outer layer called a patina.

Answer 2

Answer:

Corrosion is a natural process that converts a refined metal into more chemically stable form such as oxide, hydroxide, or sulfide.

Copper vessels turn green in passage of time due to chemical reaction with elements.
