Explanation:due displacement reaction irin us more reactive

Answer 2

Answer:

Explanation:

When iron nails are added to copper sulphate solution and heated the blue colour of the copper solution will fade and the iron nail becomes brownish in colour. This is because Iron is more reactive than copper hence displaces copper from copper sulphate solution and form Iron sulphate solution

The chemical reaction involved is:

$Fe(s)+{}CuSO_{4 }(aq)$   ⇒ $FeSO_{4}(aq) +Cu(s)_{}$
