Questions and Answers

Why did Arrhenius' theory fail to explain the behavior of some compounds like NH3?

  • It failed to address the behavior of noble gases
  • It focused only on aqueous systems
  • It did not consider the reaction with hydrogen chloride
  • It could not explain the behavior of compounds without hydroxyl ions (correct)

    • According to Arrhenius, how is an acid defined?

  • A substance that releases oxygen gas
  • A substance that liberates hydrogen ions, H+ (correct)
  • A substance that supplies hydroxyl ions, OH−
  • A substance that reacts with water molecules

    • Why is the Brönsted–Lowry theory considered more useful than the Arrhenius theory?

  • It can represent ionization in both aqueous and non-aqueous systems (correct)
  • It uses a different set of chemical symbols
  • It focuses only on strong acids and bases
  • It was proposed earlier than the Arrhenius theory
