What is the difference between displacement and double displacement reactions ? Write equations for these reactions.

Text Solution

Verified by Experts

In displacement reactions , more reactive metal displacess less reactive metal from its aqueous salt solutions
Ex: `CuSO_(4)+FerarrFeSO_(4)+Cudarr`

In double displacement reaction, exchange of ions takes place when the aqueous solutions of two salts get mixed together .
E.x: `NaCl+AgNO_(3)rarrAgCl(darr)+NaNO_(3)`
