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
Answers (1)
Ans. (b)
We know that Ag is less reactive than Mg, Zn and Cu.
Hence Silver (Ag) metal would be displaced from the solution of its salts by other three metals.
Mg + 2 AgCl MgCl2 + 2 Ag
Zn + AgCl ZnCl2 + Ag
Cu + 2 AgCl CuCl2 + 2 Ag
Therefore option (B) is correct
