Answer 1

Explanation:

A solution of copper sulphate was kept in iron vessel. The following reaction takes place :

\sf{Fe\:+\:CuSO_4\:\rightarrow\:FeSO_4\:+\:Cu}

As Fe is more reactive than Cu (according to reactivity series) so, it displaces Cu from CuSO4 and react with Fe to give FeSO4 and Cu.

Here.. more reactive metal displaces less reactive metal from it's salt solution. So, it is knwon as Displacement reaction.

Now, again coming back to the question.

Iron is more reactive than copper due to this it displaces copper from it's solution. After that reaction (which is shown above) iron becomes ferrous sulphate.

Since, iron is consumed holes appear on the vessel.

hope it helps you.....!!
