Answer:
Explanation:
Corrosion on silver items is called tarnishing which can be easily removed by adding silver idols in boiling water along with baking soda and aluminum foil.
This can electro-chemically reverse the tarnish of silver and make it shiny without causing loss of silver.
tarnish can also be removed by dipping silver in lime-lemon liquid.
