  • Acid dissociation constant
    Measures the strength of an acid by its ability to donate protons in solution.
  • Base ionization constant
    Quantifies a base's ability to accept protons in solution.
  • Monoprotic acid
    An acid that donates only one proton or hydrogen atom per molecule to an aqueous solution.
  • Equilibrium expression
    A formula representing the ratio of products to reactants, excluding liquids and solids.
  • Conjugate acid-base pair
    Consists of two species that transform into each other by gain or loss of a proton.
  • Ionization constant for water
    The product of the acid and base dissociation constants for conjugate pairs.
  • pKa
    The negative logarithm of the acid dissociation constant, indicating acid strength.
  • pKb
    The negative logarithm of the base ionization constant, indicating base strength.
  • Kw
    The ionization constant for water, equal to the product of H+ and OH- concentrations.
  • H3O+
    The hydronium ion, formed when water accepts a proton from an acid.
  • A-
    The conjugate base formed when an acid donates a proton.
  • Strong acid
    An acid with a high Ka value, indicating complete dissociation in solution.
  • Weak acid
    An acid with a low Ka value, indicating partial dissociation in solution.
  • Strong base
    A base with a high Kb value, indicating complete ionization in solution.
  • Weak base
    A base with a low Kb value, indicating partial ionization in solution.
