Question

All of the following metals can displace
aluminium from its salt solution except​

Answer 1

Answer:

In a displacement reaction, a more reactive metal of the activity series can displace a less active one in its salt solution. Reactivity order is:

Mg>Zn>Cu>Ag.

Thus, we see that Ag is least reactive and of the given four metals, Ag would be displaced from the solution of its salts by other three metals.
