Study Notes
Electrolytes
- Electrolytes are substances that form ions when dissolved in water.
- Non-electrolytes do not ionize and remain as molecules in water.
- Electrolytes are categorized as strong or weak based on their degree of ionization in dilute solutions.
Strong Electrolytes
- Strong electrolytes ionize completely (or almost completely).
- Examples include strong acids, strong bases, and salts.
Weak Electrolytes
- Weak electrolytes ionize to a lesser extent in water.
- Examples include weak acids and weak bases.
- Weak electrolytes partially dissociate in solution.
- An equilibrium exists between ions and non-ionized molecules.
- Ionization is represented by a double arrow indicating equilibrium.
