3 difference between displacement n double displace ment reactions

Displacement reaction is a reaction in which one element displaces the other from its compound.

Example: 2A gNO 3 (aq)+Cu Cu (NO 3 ) 2 (aq) + 2Ag (s)

Double displacement reaction is the reaction in which two different ions or group of ions are displaced from their respective compounds by each other.

Example: Na2SO 4+ BaCl 2 (aq) BaSO 4 (s) + 2NaCl (aq)

AND

Displacement reaction: The reaction in which one element displaces another element from its compound is known as displacement reaction. In these reactions, more reactive element displaces less reactive element from its compound.

Example- 2AgNO 3 (aq) +Cu Cu (NO 3 ) 2 (aq) + 2Ag (S) Silver nitrate Copper Copper nitrate Silver In the above reaction, Silver is replaced by copper because copper is more reactive than silver.

  • Double displacement reaction: The reaction in which two different atoms or group of atoms (ions) are displaced by other atoms or group of atoms (ions) is known as double displacement reaction.

  • Example Na 2 SO 4 ( aq) + BaCl 2 (aq) BaSO 4 (s) + 2NaCl(aq) Sodium Sulphate) (Barium chloride) (Barium Sulphate) (Sodium Chloride ) Here, SO 42 - displaces Cl - ions and Cl - ions displace SO 42 - ions or both ions exchange each other. These reactions occur in ionic compounds.

Displacement reactions are those in which an uncombined single element simply replaces the other in a compound. A general chemical equation for reaction is

AB + X → AX + B

For example

A Double Displacement Reaction on the other hand is a reaction involving two molecules in which parts of two compounds are exchanged to give two new compounds. The general equation used to represent double displacement reactions can be written as:

AB + CD → AD + BC

For example

Thus, single displacement reaction is the reaction between an element and a compound, while a double displacement reaction is the reaction between two compounds.Also, a single displacement reaction leads to the formation of a new compound and deposition of a new element, while a double decomposition reaction leads to the formation of two new compounds.
