Question

Is it safe to go swimming in the ocean while wearing silver jewelry? Why?

Yes it is safe because Na+ is not strong enough of a reducing agent to reduce Ag.

No it is not safe because Na is a strong reducing agent and will reduce the Ag.

Yes it is safe because Na+ is not strong enough of an oxidizing agent to oxidize Ag.

No it is not safe because Na+ is a strong oxidizing agent and will oxidize the Ag.

Answer 1

Yes it is safe because Na+ is not strong enough of a reducing agent to reduce Ag. (correct)

No it is not safe because Na is a strong reducing agent and will reduce the Ag. (Wrong, correct statment about Na, but elemental Na is not present in ocean)

Yes it is safe because Na+ is not strong enough of an oxidizing agent to oxidize Ag. (Correct, Ag is strong oxidizing agent)

No it is not safe because Na+ is a strong oxidizing agent and will oxidize the Ag. (wrong)

Na+ is neither a reducung agent nor an oxidizing agent. Only elemental Na is strong reducing agent.
