  • Diprotic Acid
    A compound capable of donating two H+ ions, typically represented by the formula H2A.
  • H2A
    The general formula for a diprotic acid, indicating two acidic hydrogens and a nonmetal portion.
  • Ka1
    The acid dissociation constant for the first ionization of a diprotic acid, larger than Ka2.
  • Ka2
    The acid dissociation constant for the second ionization of a diprotic acid, smaller than Ka1.
  • Conjugate Base
    The species formed when an acid donates an H+ ion.
  • Conjugate Acid
    The species formed when a base accepts an H+ ion.
  • Equilibrium Expression
    A mathematical representation of the ratio of products to reactants, excluding solids and liquids.
  • Kb1
    The base dissociation constant for the first ionization of a diprotic base, larger than Kb2.
  • Kb2

  • Amphoteric
    A substance capable of acting as either an acid or a base.
  • Intermediate Form
    The form of a diprotic acid or base after losing or gaining one H+ ion.
  • Basic Form
    The form of a diprotic acid or base after losing all H+ ions.
  • Monoprotic Acid
    An acid that donates only one H+ ion, used as a comparison for H2A.
  • pH
    A measure of the acidity or basicity of a solution, related to H+ ion concentration.
