Question

What changes do you observe in the iron nails and colour of copper sulphate solution, if iron nails are dipped in cuso solution for 15 minutes ?

Answer 1

When iron nails are dipped in CuSO4 then
1.the iron nails get covered with brown coloured copper
2. The blue colour of copper sulphate faded and become pale green

Answer 2

When an iron nail is dipped in copper sulphate solution, a brown coating of copper is formed in the surface of iron and the colour of copper sulphate solution changes from blue to pale green. The reaction shows that iron is more reactive than copper because it displaces copper from the copper sulphate solution.
