How do gold smith cleans silver ornaments write the chemical reaction involved

Answer 1

Ag2S + 2 Al → 6 Ag + Al2S3 silver sulfide + aluminum → silver + aluminum sulfide
Drop silverware in the pot for 10 seconds (longer if it's very tarnished), then remove using kitchen tongs. Magic! Here's how to polish silver if the built-up tarnish persists: make a thick paste with 1/4 cup baking soda and two tablespoons of water. Apply with a damp sponge, then rinse and dry

Answer 2

Hey dear,

● Cleaning silver ornaments -
- Over the years silver ornaments gets tarnished to dull gray color.
- This is due to formation of silver sulphide coat on the ornaments.
- This silver sulphide is converted back into silver by addition of more reactive metal like aluminum.

Silver sulphide + Aluminium ---> Silver + Aluminium sulphide
3Ag2S + 2Al ---> 6Ag + Al2S3

Hope this helps you...
