A substance that completely dissociates into ions when dissolved in water, producing a highly conductive solution. Strong electrolytes include strong acids (HCl, HNO₃), strong bases (NaOH), and soluble ionic salts (NaCl). Virtually no undissociated molecules remain in dilute solution.
Properties & Characteristics
A strong electrolyte is a substance that completely dissociates into ions when dissolved in water, giving a solution with high electrical conductivity. Examples include strong acids (HCl, H₂SO₄), strong bases (NaOH, KOH), and most ionic salts. The degree of dissociation (α) is essentially 1 for strong electrolytes. Their solutions obey the limiting law of Debye-Hückel for ion activities.
Uses & Applications
Strong electrolytes are used as conducting media in electrochemical cells and batteries. Industrial electrolysis processes use strong electrolyte solutions (brine, H₂SO₄). Strong electrolyte solutions are used as buffers and standards in electroanalytical chemistry.
Safety Information
Strong electrolytes include highly corrosive acids and bases. Concentrated solutions of strong electrolytes are particularly hazardous and require appropriate PPE and handling procedures.
