Question

describe displacement reaction​

Answer 1

Answer:

Displacement reactions occur when a metal from the electrochemical series is mixed with the ions of a metal lower down in the electrochemical series. The atoms of the more reactive metal push their electrons on to ions of the less reactive metal.

Answer 2

Displacement reactions occur when a metal from the electrochemical series is mixed with the ions of a metal lower down in the electrochemical series. The atoms of the more reactive metal push their electrons on to ions of the less reactive metal.

A single displacement reaction which is also called as single replacement reaction is a kind of oxidation-reduction chemical reaction when an ion or element moves out of a compound, i.e., one element is replaced by the other in a compound.

When chlorine is added in its gaseous form (or as a gas dissolved in water) to the solution of sodium bromide, the chlorine acquires the place of bromine. Since chlorine is more reactive than bromine, it displaces bromine from sodium bromide, and the solutions turn blue. The brown colour is the bromine that is displaced. If you notice the equation, you can see that the Cl and Br have swapped their original places.chlorine + sodium bromide → sodium chloride + bromineCl2(aq) + 2NaBr(aq) → 2NaCl(aq) + Br2(aq)

Let’s analyse another chemical reaction.

Dissolve 0.5 gm of Silver nitrate in 10 ml of water in a test tube. A copper wire is then dipped in it and kept undisturbed for some time. The shining silver crystals are visible on the Copper wire. The solution becomes bluish as some amount of copper is developed. In the below reaction, the copper metal displaces silver from Silver Nitrate solution.Cu(s) + 2AgNo3(aq) → 2Ag(s) + Cu(NO3)2(aq)
