  1. Arrhenius theory
    Acids produce Hydronium Iions, H3O+ in aqueous solutions. Bases produce hydroxide ions, OH- in aqueous soltions by dissociation of ions and reaction with water.
  2. Bronsted-Lowry
    Does not require water as the solvent. Acid is a proton donor. Base is a proton acceptor. Conjugate bases.
  3. strong acids
    • in water, produce almost 100% H3O+
    • (equilibrium is far to the right - K is large)
  4. weak acids
    • in water, produce very little H3O+
    • (equilibrium is far to the left - K is small)
  5. strong bases
    • in water, produce
    • almost 100% OH- (equilibrium is far to the right – K is large)
  6. weak bases
    • in water, produce very little OH-
    • (equilibrium is far to the left - K is small)
  7. monoprotic
    HCl, HSO4-
  8. diprotic
    H2SO4, H2PO4-
  9. triprotic
    H3PO4
  10. amphiprotic
    except for H2O, the amphiprotic substance will be negatively charged and contain a H at the beginning of the chemical formula
  11. position of the equilibrium
    • the position of the equilibrium is shifted
    • away from the stronger acid, i.e. to the opposite side
  12. the strength of a weak acid
    determined by the acid ionization constant, Ka - the greater its value, the stronger the acid
  13. equilibrium expression?

    H2CO3 + H2O <--> H3O+ + HCO3-
    • Keq = [H3O+][HCO3-]
    • [H2CO3][H2O]
