AP Chemistry Unit 4.8 Introduction to Acid-Base Reactions

Introduction to Acid-Base Reactions

  • Arrhenius concept: acids produce H+ in solution, bases produce OH- ion (but what about NH3?)
  • Bronsted-Lowry: An acid is a proton (H+) donor. A base is a proton acceptor
  • Lewis Acids: electron-deficient molecules (+)
  • Lewis Base: Electron-rich molecule (-)
  • Conjugate base: what an acid becomes after it donates a proton
  • Conjugate acid: what a base becomes after it receives a proton
