Question

When silver tarnishes, ag atoms are oxidized to form ag+ ions. ag atoms are reduced to form ag+ i?

Answer 1

Answer;

Ag atoms are oxidized to form Ag+ ions

Explanation;

• Silver tarnish is the result of the oxide on the silver surface reacting with hydrogen sulfide (H2S) in air. This leaves a black film of silver sulfide (Ag2S). Silver atoms are oxidized to form Ag+ ions.
• When a thin coating of silver sulfide forms on the surface of silver, it darkens the silver.
• The offending silver tarnish can be removed by either striping it from the surface or reversing the chemical reaction and turn silver sulfide back into silver.
