Give difference between displacement and double displacement reactio...
Example- 2AgNO3 (aq) +Cu   Cu (NO3)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 �Na2SO4(aq) + BaCl2 (aq)  BaSO4(s) + 2NaCl(aq)

(Sodium Sulphate) (Barium chloride) (Barium Sulphate) (Sodium Chloride )

Here, SO42- displaces Cl- ions and Cl- ions displace SO42- ions or both ions exchange each other. These reactions occur in ionic compounds.

Give difference between displacement and double displacement reactio...
In displacement reaction , one element from its salt is displaced by a more reactive element. e.g. , Cu is displaced by Zn from CuSO4 because Zn is more reactive.

CuSO4 + Zn -----> ZnSO4 + Cu


In double displacement reaction exchange of ions takes place between two reactants to form new products.

Na2SO4 + BaCl2 -----> BaSO4 + 2NaCl

Give difference between displacement and double displacement reactio...
In displacement reaction the more reactive substance displaces less reactive substance from its salt solution where as in double displacement reaction there is exchange of ions.
eg of displacement reaction- Zn + feso4=zn so4+fe
eg of double displacement reaction- Na2so4+Bacl2= Baso4+2Nacl
