Study Notes
Electrolytes Overview
- Electrolytes are substances that dissociate into ions in water and conduct electricity.
Strong Electrolytes
- Complete dissociation into ions in solution.
- Examples include:
- HCl (hydrochloric acid)
- HBr (hydrogen bromide)
- HI (hydrogen iodide)
- HClO₄ (perchloric acid)
- HNO₃ (nitric acid)
- H₂SO₄ (sulfuric acid)
- NaOH (sodium hydroxide)
- KOH (potassium hydroxide)
- All soluble ionic compounds
Weak Electrolytes
- Exist primarily as neutral molecules, with only a small fraction as ions.
- Examples include:
- CH₃CO₂H (acetic acid)
- HF (hydrofluoric acid)
- NH₃ (ammonia, also a weak base)
- HCN (hydrogen cyanide)
Non-Electrolytes
- Do not dissociate in solution and do not conduct electricity.
- Common examples:
- H₂O (water)
- CH₃OH (methanol)
- C₂H₅OH (ethanol)
- C₁₂H₂₂O₁₁ (sucrose)
Summary Lists
- Strong Electrolytes: HCl, HBr, HI, HClO₄, HNO₃, H₂SO₄, NaOH, KOH
- Weak Electrolytes: CH₃CO₂H, HF, HCN, NH₃
- Nonelectrolytes: H₂O, CH₃OH, C₂H₅OH, C₁₂H₂₂O₁₁
Key Concepts
- Strong electrolytes facilitate electrical conduction in solutions.
- Weak electrolytes provide limited ionization and thus lower conductivity.
- Nonelectrolytes dissolve in water without ion formation, leading to non-conductive solutions.
