Question

if copper rod is dipped in ironsulphate solution will reaction take place? why? ​

Answer 1

Explanation:

yes when Cu is dipped in FeS solution Cu will replace Fe and form CuS because Cu is more reactive than iron

Answer 2

I think no cause the reactivity of copper is way lesser than iron so a reaction won't take place

Fun fact:::    Cu has 4 electrons in its outermost orbit whereas Fe has two electrons in its outer most orbit. For metal stability depends on how easily they lose the electrons during bonding. Since it is easier to lose 2 electrons than 4.So Fe is more reactive than Cu or Cu is less reactive than Fe.
