When a metal is placed in the salt solution of another metal and a reaction occurs, what does it indicate about the two metals?
The solid metal is more reactive than the metal in solution
A displacement reaction occurs only when the solid metal is more reactive than the metal present in the salt solution; the more reactive metal displaces the less reactive metal from its salt.
Hence, a reaction occurring shows that the solid metal is more reactive than the metal in solution.
