Question

The black tarnish that forms on silver objects is primarily Ag2S.the half reaction for reversing the tarnishing process is as follows:

 

a.predict which of the following can reduce Ag2S to Ag under standard condition(Use data from the Standard Reduction Potential table)

 

•H2(aq)

 

•Zn(s)

 

•l-(aq)

 

•Sn2+(aq)

 

b.Of those mentioned in (a),identify which is the strongest reducing agent in aqueous solution and thus the best candidate for a commercial product.

 

c.Suggest an alternative reducing agent that is readily available,inexpensive and possibly more effective at removing tarnish(Use data from the Standard Reduction Potential table)
