Question

why iron can replace copper from copper sulphate solution but copper cannot replace iron from iron sulphate​

Answer 1

Answer:

In a displacement reaction, only a more reactive metal can replace a less reactive metal so as a less reactive metal cannot displace a more reactive metal.

Iron is more reactive than copper.

Therefore copper cannot displace iron from its salt solution.

Cu + FeSO4 = No reaction..remains same

While iron can replace copper from copper sulphate solution because iron is more reactive.
