12. The tarnish of silver objects is a coating of silver sulfide, Ag2S, which can be removed by putting the silver in contact with aluminum metal in a dilute solution of baking soda or salt. The cleaning reaction is 2Ag2Sis) + 2Al(s) → 6 Ag(s) + A12S3(s) The sulfur in these compounds has an -2 oxidation number. What is the oxidizing agent in the cleaning reaction? Oa. a. Ag2S(s) b. Al(s) C. Ag(s) d. Al2S3(s) e. There...

A student is attempting to reverse the tarnishing (silver sulfide, Ag2S(s), formation) on her silver necklace using a method she found online. She lined a bowl with aluminum foil, added some baking soda, a sprinkling of table salt, and finally boiling water. She then placed the tarnished silver object into the water, making sure there was contact between it and the aluminium foil. Amazingly, the silver sulphide tarnish began to disappear, being replaced by discoloration of the Al foil. The...
