Question

Shame on brainy people no one answers me why pls answer this pictures question​

Answer 1

Required Answer:-

The blue colour solution is:

• Copper sulphate solution (in aqueous state). It is also known as blue vitrol.

What happens in this reaction?

• The above reaction shows the displacement reaction where a more reactive metal displaces a lower reactive metal from its salt solution.

• Iron is more active than copper. Hence it displaces copper from copper sulphate and forms ferrous sulphate.

• The colour of the solution changes due to the formation of ferrous sulphate which is green. And the displaced copper accumulates on the iron nail giving it a reddish brown appearance.

• This is a slow reaction. If we put a setup of the above and wait till hours, we can see the above result$.$
