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.

Frequently Asked Questions
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.
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).
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.
The formula or notation for Electrolyte is: Ka = [H⁺][A⁻]/[HA]
