Strong electrolyte

Definition

A strong electrolyte is a substance that completely dissociates into ions when dissolved in water, resulting in high electrical conductivity. Examples include most salts, strong acids, and strong bases.

5 Must Know Facts For Your Next Test

1. Strong electrolytes dissociate 100% into ions in aqueous solutions.
2. They exhibit high electrical conductivity due to the presence of free-moving ions.
3. Examples include sodium chloride (NaCl), hydrochloric acid (HCl), and potassium hydroxide (KOH).
4. In contrast to weak electrolytes, the ionization of strong electrolytes is not reversible.
5. Strong electrolytes are crucial in many chemical reactions and industrial processes due to their ability to conduct electricity efficiently.

Review Questions

Related terms

Weak Electrolyte:

A substance that partially dissociates into ions in solution, resulting in lower electrical conductivity compared to strong electrolytes.

Non-Electrolyte: A substance that does not produce ions when dissolved in water, thus it does not conduct electricity.

Dissociation:

The process by which molecules split into smaller particles such as atoms, ions, or radicals, usually in a reversible manner.
