Difference between displacement and double displacement reaction . Give equation?

Question

Answer

Displacement reactions-

1.in these reactions, more active element displaces less active element from its salt solution.

2.these reactions are usually slow and take longer time for their completion.

3.one of the reactantis in solid state and other reactants is in aqueous state.

4.during these reactions usually change of colour takes place.

5.Fe(s)+CuSO4(aq)=>FeSO4(aq)+Cu(s)
*Double displacement reactions-

1.in these reactions,there is an exchange of ions between two reactants.

2.these reaction are usually fast and place instantaneously.

3.both the reactants are in aqueous state.

4.during these reactions usually precipitates are formed.

5. Na2S+2HCl→2NaCl+H2S

Answer

Chemical Displacement Reaction:-

* More reactive element displaces less reactive
element in a compound.
* Reaction occurs very slowly.

Examples :- (i) CuSO4 (aq) + Zn (s) ––> ZnSO4 (aq) + Cu (s) ↓
(ii) Pb + CuCl2 (aq) ––> PbCl2 (aq) + Cu (s) ↓

Chemical Double Displacement Reaction:-

* Mutually exchange their ions in two compounds.
* Reaction occurs very fast.

Examples :- (i) Na2SO4 + BaCl2 ––> BaSO4↓ + NaCl
(ii) BaCl2 + H2SO4 ––> BaSO4↓ + HCl.

Answer

Difference between Displacement and Double Displacement Reactions
Displacement and double displacement reactions are two fundamental types of chemical reactions that differ in their mechanisms and products formed.
Displacement Reaction
- In a displacement reaction, one element replaces another in a compound.
- This type of reaction generally involves a more reactive element displacing a less reactive one.
- The general form can be represented as:
- A + BC → AC + B
*Example:*
- Zn + CuSO4 → ZnSO4 + Cu
Characteristics of Displacement Reactions
- Single Replacement: Only one element is displaced.
- Reactivity: The reactivity series plays a crucial role; only more reactive metals can displace less reactive metals.
- Energy Changes: Often exothermic, releasing energy.
Double Displacement Reaction
- In a double displacement reaction, components of two compounds exchange places.
- This reaction usually occurs in aqueous solutions where ionic compounds are involved.
- The general form can be represented as:
- AB + CD → AD + CB
*Example:*
- Na2S + BaCl2 → BaS + 2NaCl
Characteristics of Double Displacement Reactions
- Ion Exchange: Involves the exchange of ions between two compounds.
- Precipitation: Often results in the formation of a precipitate or gas.
- Neutralization: Commonly seen in acid-base reactions.
Key Differences
- Type of Reaction: Displacement involves one element replacing another, while double displacement involves the exchange of partners between two compounds.
- Number of Reactants: Displacement has one reactant and double displacement has two.
- Products Formed: Displacement forms one compound and one free element, while double displacement yields two new compounds.
Understanding these reactions is essential as they form the basis for many chemical processes in both laboratory and industrial settings.
