Question

Iron cannot be replaced by copper from its salt solution- Give reason

Answer 1

Hey!

iron is a more reactive metal than copper, so copper cant replace iron from its salt solution but iron can replace copper from its salt solution.

Here's an activity----

Iron sulphate (solution)+ copper_ gives
'no reaction'

Copper sulphate(blue in colour)+Iron --> Iron suulphate(solution turned into green colour)+copper (brownish substances settle down in the solution, that is copper)

Hope it helped u :)

Answer 2

It is because iron is more reactive than copper and a less reactive metal cannot displace a more reactive one.
