Question

Which one of the following four metals would be displaced from the solution of its salt by the other three metals?

Options

• Zn

• Ag

• Cu

• Mg

Answer 1

Ag

Explanation:

In a displacement reaction, a more reactive metal displaces a less reactive metal from its salt solution. According to the reactivity series, the order of reactivity for these four metals is Mg > Zn > Cu > Ag. Since silver (Ag) is the least reactive metal among them, it lacks the power to displace any of the others and will easily be displaced from its salt solution by magnesium, zinc, and copper.
