उत्तर
| Dissociation | Ionisation | |
| (1) | Separation of ions which are already present in an ionic compound. | Formation of positively or negatively charged ions from molecules which are not initially in the ionic state. |
| (2) | Electrovalent compounds show dissociation, e.g., potassium chloride, lead bromide, etc. \[\ce{KCl -> K+ + Cl-}\] |
Polar covalent compounds show ionisation, e.g., HCl, NH4OH, etc. \[\ce{HCl->[H2O]H+ + Cl-}\] |
