Question

what heppen when iron blade/deeped into copper sulphate solustion​

Answer 1

Answer:

Explanation:

the iron displaces the copper from the copper sulphate to form iron sulphate because of displacement reaction, As Iron is a stronger element it displaces copper from the solution.

here is the chemical equation :

Fe + CuSO4 = Cu + FeSO4

pls mark me brainliest

Answer 2

Fe(s)+ CuSO Cu(s)+ FeSO

4 ⟶ 4

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 asFe2+ions and ferrous sulphate solution is formed.
