NCERT Activity 3.12 Class 10 Science Explanation

In this post, you will find NCERT Activity 3.12 Class 10 Science Explanation that belongs to Chapter 3 Metals and Non-metals. After reading Solutions of chapter 3 Metals and Non-metals, you will be able to understand activity 3.12.

NCERT Activity 3.12 Class 10 Science Explanation


Activity 3.12 Class 10 Science

·      Take a clean wire of copper and an iron nail.

·      Put the copper wire in a solution of iron sulphate and the iron nail in a solution of copper sulphate taken in test tubes.

·      Record your observations after 20 minutes.

·      In which test tube did you find that a reaction has occurred?

·      On what basis could you say that a reaction has actually taken place?

·      Can you correlate your observations for the activities 3.9, 3.10 and 3.11?

·      Write a balanced chemical equation for the reaction that has taken place.

·      Name the type of reaction.

NCERT Activity 3.12 Class 10 Science Explanation

Observations and Conclusion:

(i) Reaction occurs in the test tube containing iron nail dipped in a copper sulphate solution.

(ii)   The copper sulphate solution fades the light colour due to the formation of iron (II) sulphate appears.

(iii)At the same time, a brown deposit of copper takes place on iron nails.

(iv) Thus, the following reaction takes place:

Fe(s)   +  CuSO4(aq)   → FeSO4(aq)  +      Cu(s)

Iron     Copper sulphate    Iron (II) sulphate      Copper

(v)    Iron is more reactive than copper and displace from copper sulphate solution.

(vi)  A more reactive metal displaces a less reactive metal from its salt in the solution. This is called displacement reaction.
