Weak electrolytes are caused by their partial dissociation into ions when dissolved in a solution, which limits their ability to conduct electricity effectively. The types of weak electrolytes include weak acids and weak bases.
Understanding Weak Electrolytes
Weak electrolytes don't fully break down into ions in a solution. This limited ionization means fewer charge carriers (ions) are available, resulting in poor electrical conductivity.
Key Characteristics
- Partial Dissociation: Unlike strong electrolytes, weak electrolytes only dissociate partially into ions when dissolved in a solvent.
- Weak Conductivity: Due to the limited number of ions in solution, they are weak conductors of electricity.
- Equilibrium: An equilibrium exists between the undissociated compound and its constituent ions.
Examples of Weak Electrolytes

Mercury(II) Chloride | Weak Electrolyte |
Factors Affecting Weak Electrolytes
- Nature of the Solute: The chemical structure and properties of the solute determine its ability to dissociate.
- Solvent Properties: The polarity of the solvent affects the ionization process.
- Temperature: Temperature changes can shift the equilibrium between ions and undissociated molecules.
