A reaction in which two ions switch places is called double-displacement reaction.
Explanation:
Double displacement reaction usually takes place between two positive ions or two negative ions. When anions or cations of totally different compounds change places, two totally different compounds are formed.
<u>Syntax for double displacement reaction:
</u>
AB + CD --> AD + BC
It can also be defined in simple terms as the reaction in which exchange of ions takes place is called double displacement reaction.
The chemical reaction is as follows:
NaOH(aq) + HCl(aq) --> NaCl(aq) + H2O (l)
