Question

when a chemical reaction between aqueous silver nitrate and aqueous sodium chloride is carried out,white precipitateof silver chloride are formed. The above reaction is an example of :
a)Displacement reaction
b)double displacement reaction
c)decomposition reaction
d)combination reaction

Answer 1

This is a double displacement reaction. The reaction is as follows
${\text{AgNO}}_3+\text{NaCl}\to \text{AgCl}+{\text{NaNO}}_3$
So we can see that participated ion gets exchanged which is called double displacement reaction.
