Electrolyte

Ka = [H⁺][A⁻]/[HA]
Quick Reference
Formula / NotationKa = [H⁺][A⁻]/[HA]
Also Known AsIonic conductor, ion-forming substance, strong/weak electrolyte

What is Electrolyte?

A substance that dissociates into ions when dissolved in water or when melted, allowing the solution to conduct electricity. Strong electrolytes (strong acids, strong bases, soluble salts) completely dissociate, while weak electrolytes only partially dissociate.

Formula & Notation

Ka = [H⁺][A⁻]/[HA]

Other Names / Synonyms: Ionic conductor, ion-forming substance, strong/weak electrolyte

Properties & Characteristics

An electrolyte is a substance that produces ions when dissolved in water (or other polar solvents), thereby making the solution electrically conductive. Strong electrolytes (strong acids, strong bases, most salts) fully dissociate; weak electrolytes (weak acids, weak bases) partially dissociate. Non-electrolytes (glucose, ethanol) do not ionise. Equivalent conductivity and Kohlrausch's law describe the conductivity of electrolyte solutions.

Uses & Applications

Electrolytes are essential in batteries and fuel cells (as ion-conducting media), in biological fluid balance (Na⁺, K⁺, Cl⁻ regulate nerve function and osmolarity), in electroplating baths, in industrial electrolysis, and in clinical medicine (oral rehydration therapy, IV fluids).

Safety Information

Concentrated electrolyte solutions of acids and bases are corrosive. In batteries, electrolyte leakage (H₂SO₄ in lead-acid, KOH in alkaline cells) causes chemical burns. Lithium-ion battery electrolytes (LiPF₆ in organic solvents) are flammable and release HF on decomposition.

Always consult the SDS/MSDS before handling any chemical. This information is for educational purposes only.
