A cation will not replace an anion in a compound because the two positively-charged ions will repel each other.
<h3>Ions</h3>
Ions are atoms or group of atoms possessing an electrical charge.
- Positively-charged ions are known as cations.
- Negatively-charged ions are known as anions.
<h3>Ionic compounds</h3>
Ionic compounds are compounds which are composed of oppositely charged ions held together by strong electrostatic forces of attraction between the oppositely charged ions.
- From law of electrostatics, like charges repel and unlike charges attract.
If a cation replaces an anion, the compound would have two l positive charges which will repel each other.
Therefore, a cation will not replace an anion in a compound because the two positively-charged ions will repel each other.
