Write the definition of displacement reaction. Give one example of it

1.	Write the definition of displacement reaction. Give one example of it and explain, how is it different from double displacement reaction.
Answer» Solution :The REACTION in which more reactive metal DISPLACES the LESS reactive metal from its COMPOUND is called as displacement reaction. For example, `Fe(s)+CuSO_(4)(aq) to FeSO_(4)(aq) +Cu(s)` This reaction is different than double displacement reaction. In double displacement reaction ions get exchanged in two compounds. For example, `Na_(2)SO_(4)(aq) +BaCl_(2) (aq) to BaSO_(4)(s) +2NaCl(aq)` In short, one ion gets exchanged in displacement reaction, while two ions are exchanged in double displacement reaction.
