Question

what happen when copper sulphate is stored in an iron beaker​

Answer 1

In this case, iron, being more reactive than copper, will displace it from the solution. That is, ferrous ions or Fe(II) will go into the solution, while curic or Cu(II) will be deposited onto the nail. This cause the solution color to change from blue to green.

Answer 2

Answer:

Cu rEact with iRon. Iron is more electro positive than Copper. Or Copper is less reactive than Iron.

So when an iron nail is dipped in a solution of CuSO4, it displaces copper from the Solution, which gets deposited or precipitated as a red or red-brown residue.

Also the blue colour of the solution gradually fades. Ultimately the solution becomes pale green in colour due to the formation of ferrous sulphate. This happens when all the copper is displaced from the solution of copper sulphate.

Fe + CuSO4 ———-> FeSO4 + Cu
