Question

what is displacement reaction​

Answer 1

A displacement reaction is a type of reaction where part of one reactant is replaced by another reactant. A displacement reaction is also known as a replacement reaction

Answer 2

Answer :-

Displacement reaction:- The reaction in which a reactive metal displaces the less reactive metal from its salt solution is called displacement reaction .

Displacement reaction also known as substitution reaction.

Example:-

Zn + CuSO4 → ZnSO4 + Cu

• here, Zn is a reactive metal which displace the copper less reactive metal from its salt solution and form Zinc sulphate which is white in colour and the blue colour of copper sulphate is faded away.

2) Cu + AgSO4 → CuSO4 + Ag

3) Na + ZnSO4 → NaSO4 + Zn

You can use reactivity series to find which metal is more reactive and which is less reactive .

• See in attachment.

Displacement reaction in Non - metals:-

Displacement reaction is also shown by Non- metals.

Non - metals which is more reactive in nature displace less reactive non - metal.

Example:-

2NaBr + Cl2 → 2NaCl + 2Br

here, Chlorine and bromine are both non - metals belongs to halogen group .

Chlorine is more reactive than Bromine so it displaces the bromine from sodium bromide and form Sodium chloride.
