Are neutralization reactions double displacement reactions?

Double displacement reactions are reactions in which elements (ions, atoms) are exchanged between two compounds.

Ex-  `2NaOH + CuSO_4 →Cu(OH)_2    +   Na_2SO_4`

Sodium hydroxide forms `Na^(+)  + OH^(-)` ions

`NaOH   →Na^(+)  + OH^(-)`

Copper sulphate also ionised in solution

`CuSO_4   →  Cu^(2+)  + SO_4^(2-)`

Exchange of ions

`Na^(+)  + SO_4^(2-)   → Na_2SO_4`

`Cu^(2+)  +   OH^(-) → Cu(OH)_2`

 

So, in the double displacement reaction, the exchange of  ions takes place and two new products are formed.

Neutralization reactions are the reactions in which reactants are acid and base. They react to produce salt and water. So, the exchange of ions between acid and base also takes place that’s why neutralization reactions can be considered as double displacement reactions.

`NaOH  + H_2SO_4   → Na_2SO_4  + H_2O`

Sodium hydroxide ionised in the solution

`NaOH  →Na^(+) +  OH^(-)`

Sulphuric acid ionised in the solution

`H_2SO_4  →  2H^(+)  + SO_4^(2-)`

Exchange of ions

`Na+ +  SO_4^(2-)  → Na_2SO_4`

 

`2H^(+)  + OH^(-) → H_2O`

 

So, in the neutralization reaction, an exchange of ions takes place and two products (salt and water)  are formed.

Conclusion: Yes, all neutralization reactions are double displacement reactions

FAQs

1.  Do neutralization reactions always produce water?

Ans.- Yes, water is always one product during neutralisation reactions.

2.  Do neutralization reactions always produce salt?

Ans. – Yes, neutralization reactions always produce salt as a product and it depends on the acid and base used in the reaction.

3.  Can the neutralization reaction be reversed?

Ans.- Neutralisation reaction is a chemical change and these changes cannot be reversed.
