Which one of the following four metals would be displaced from the solution of its salts by other three metals?
(A) Mg
(B) Ag
(C) Zn
(D) Cu
Answer
The reactivity of the given metals according to the reactivity series is : Mg> Zn> Cu> Ag
Since Ag is the least reactive metal , the other metals will be able to displace Ag from its salt solution.
So, the correct answer is (b) Ag
