Question

When an iron nail is dropped into the test tube containing copper sulphate solution, the colour of the solution changes after sometime is also the iron nail gets covered with a reddish brown coating
1)which type of reaction is taking place in the test tube
2)Explain what happens in such reaction
3)what can you conclude about the metals involved in the above​

Answer 1

(1) The reaction takes place in test tube is displacement reaction.

(2)This is displacement reaction because when an iron nail is immersed or dropped in copper sulphate solution in test tube then the iron displaces copper in it's compound as iron is more reactive than copper.

(3) The copper sulphate solution turns pale green due to the displacement of iron .The reaction is

CuSO4 (aq) + Fe(s) = FeSO4 (aq) + Cu (s).

where aq = aqueous, s = solid
