Answer 1

Answer:

( i ) there is a reddish-brown deposit on the blade. equation:

$copper sulphate + iron = iron sulphate + copper$

( ii ) chemical change

Answer 2

Answer:

Fe(s)+CuSO

⟶Cu(s)+FeSO

When an iron nail is dipped in copper sulphate solution, a brown coating of copper is formed on the surface of iron and the colour of copper sulphate solution changes from blue to light green. This reaction shows that iron is more reactive than copper as it displaces copper from its solution and iron passes into solution as Fe

ions and ferrous sulphate solution is formed.
