what is displacement reaction ? explain with experiment.give equation.
log answer.
Answers
those reaction in which one element take place of another element in a compound , are known as displacement reaction...
Example...
when a strip of zinc metal is placed in copper sulphate solution , then zinc sulphate solution and copper are obtained :
CuSO4 + Zn ........ ZnSO4 + Cu..
in this reaction , zinc displace copper from copper sulphate compound so that copper is liberated.
Answer:
the reaction of an element with the compound or in simple words when the least reactive element is displaced by another or most reactive element is called Displacement or single-replacement reaction.
Explanation:
experiment for displacement reaction :-
Take a test tube, in this make 5 ml solution of copper sulphate (CuSO₄).
Now place a non rusted iron nail in the test tube. Leave it for sometime. Observe the test tube after sometime.
what will you observe -
You will see that there is deposition of thin layer of brown color on the iron nail.
THIS LAYER IS OF COPPER METAL.
The solution in the test tube also changes from blue to green, here the displacement occurs between the copper present in the solution and iron present in the iron nail, due to which iron gets in the solution and copper is deposited on the iron nail . Here more reactive metal displace less reactive metal.
iron is more reactive than copper and therefore displace copper.
equation for the above experiment :-
Fe + CuSO₄ ⇒ FeSO₄ + Cu
(iron) + (Copper sulphate) ⇒ ( Ferrous sulphate) + (copper)
