Key Concepts & Definitions

  • Arrhenius acid: An Arrhenius acid is a compound that releases hydrogen ions when dissolved in water.
  • Arrhenius base: An Arrhenius base is a compound that dissociates in water to release hydroxide ions.
  • Brønsted acid: A Brønsted acid is a proton donor that can release H+H^+.
  • Brønsted base: A Brønsted base is a proton acceptor that can capture H+H^+.
  • Conjugate acid-base pair: A conjugate acid-base pair is formed when an acid donates a proton to become a base, or when a base accepts a proton to become an acid.
