Question

Which element can displace copper from the copper sulphate solution?​

Answer 1

Answer:

Iron can displace copper from the copper sulphate solution.

Explanation:

The reason why iron can displace copper from copper sulphate solution is its more reactivity than copper.

$Fe_{}$ + $CuSO_{4}$ ⇒ $FeSO_{4}$ + $Cu_{}$

$FeSO_{4}$ + $Cu_{}$ ⇒ no reaction, since copper has less reactivity than iron, hence the reaction cannot take place.
