→What happens when iron blade is dropped in a beaker containing copper sulphate solution. State any two observations.

____________________________________

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.

→$FE(s)+CuSO_{4}$ → $Cu(s)+FESO_{4}$.

Answer 2

Answer:

The balanced equation showing reaction between iron blade and copper sulphate is:

Fe+CuSO4-------> FeSO4+ Cu.

When greyish black iron blade is dropped into a blue coloured solution of copper sulphate ,the following observations can be noticed:

1) the colour of the solution changes from blue to light green due to formation of iron sulphate.

2) the iron blade is covered by a pink deposition of copper.

This is a single displacement reaction.
