  • Amphoteric species
    A compound that can act as both an acid and a base in chemical reactions.
  • Amphiprotic species
    A type of amphoteric species that can donate or accept a proton.
  • Water
    A common amphoteric species that can donate an H+ to form OH- or accept an H+ to form H3O+.
  • Conjugate base
    The species formed when an acid donates a proton during a chemical reaction.
  • Conjugate acid
    The species formed when a base accepts a proton during a chemical reaction.
  • Polyprotic acids
    Acids that contain more than one ionizable hydrogen atom, such as H2SO4.
  • HSO4-
    A partially dissociated form of H2SO4 that can act as an amphoteric species.
  • H2PO4-
    A partially dissociated form of H3PO4 that can act as an amphoteric species.
  • HCO3-
    A partially dissociated form of H2CO3 that can act as an amphoteric species.
  • Negative charge
    A characteristic of some amphoteric species, often found at the end of their chemical formula.
  • H+
    A proton that can be donated or accepted by amphoteric species in reactions.
  • OH-
    The ion formed when water acts as an acid and donates an H+.
  • H3O+
    The ion formed when water acts as a base and accepts an H+.
