Reaction of metal with salt solution

Question 1 In a solution of silver nitrate,a copper plate is dipped.Which metal is more reactive-copper or silver?

Question 2 A solution of copper sulphate was kept in an iron pot.After few days ,the iron pot was found to have number of holes in it.Write the equation of the reaction that took place?

Question 3 what will happen if a strip of zinc is immersed in copper sulphate solution?

Question 4 A copper coin is immersed in a solution of silver nitrate for sometime.What will happen to the coin?

Reaction of metal with salt solution

When a more reactive metal is put in salt solution of a less reactive metal,then more reactive metal displace less reactive metal from its salt solution.

1) CuSO4  (aq) + Zn (s) —-> Cu (s) + ZnSO4 (aq)

Blue colour                            Reddish  colourless

                                             brown

Zn> Cu

2) Cu (s) + + ZnSO4 (aq) —–> no reaction

Cu cannot displace zinc from its salt solution

3) Ag (s) + CuSO4  (aq) —–> no reaction

Ag<Cu

4)Fe (s) + CuSO4  (aq) ——> FeSO4  (aq) + Cu (s)

                blue                        green            reddish-brown

5)Cu (s) + FeSO4  (aq) —–> no reaction

6)2 AgNO3 (aq) + Cu(s) —–> Cu(NO3)2 (aq) + 2 Ag (s)

    colourless                                               blue

Cu > Ag
