Dissociation
| Formula / Notation | AB → A⁺ + B⁻ (ionic) or AB → A• + B• (homolytic) |
|---|---|
| Also Known As | Ionisation (for ionic dissociation), thermal dissociation, ionic dissociation, fragmentation |
What is Dissociation?
The process by which a compound separates into ions or smaller molecules in solution or upon heating. Strong electrolytes completely dissociate in water, while weak electrolytes only partially dissociate. Dissociation is fundamental to understanding acid-base and ionic equilibria.

The process by which a compound separates into ions or smaller molecules in solution or upon heating. Strong electrolytes completely dissociate in water, while weak electrolytes only partially dissociate. Dissociation is fundamental to understanding acid-base and ionic equilibria.
Dissociation equilibria govern the behaviour of acids, bases, salts, and complex ions in solution. Understanding dissociation is fundamental to titration analysis, buffer chemistry, electrolyte properties, and biological ion channel function.
Dissociation of ionic compounds in water produces ions that may be toxic (heavy metal ions, cyanide). High-temperature thermal dissociation of stable molecules can produce toxic products (HCN from nitrile heating, NOₓ from organic nitrogen compounds). Assess decomposition products in any high-temper…
