Question

What happens when Iron nails are placed in copper sulphate solution? Write word equations of the reactions involved.

Answer 1

Answer:

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

2+

ions and ferrous sulphate solution is formed.

Explanation:

Fe(s) + CuSO4 => Cu(s) + FeSO4

Answer 2

Answer

-----------

When iron nail is dipped in Copper sulphate, it takes reaction between them and Copper sulphate changes its color from blue to light green. ... This could replace copper from CuSO4, and blue color and FeSO4 is in light green color. It will change its colors due to copper iron nails functions.
