  • What is an amphoteric species?
    An amphoteric species is a compound that can act as both an acid and a base.
  • Can water be considered an amphoteric species?
    Yes, water can act as both an acid and a base, making it an amphoteric species.
  • What is an example of a polyprotic acid?
    Examples of polyprotic acids include H2SO4, H3PO4, and H2CO3.
  • What happens when a polyprotic acid partially dissociates?
    When a polyprotic acid partially dissociates, it forms a conjugate base that can be amphoteric.
  • What is a common feature of amphoteric species?
    Amphoteric species often have at least one hydrogen atom and a negative charge.
  • Is water an exception to the common features of amphoteric species?
    Yes, water is an exception because it does not have a negative charge but is still amphoteric.
  • What is an amphiprotic species?
    An amphiprotic species is a type of amphoteric species that can donate or accept a proton.
  • How does water act as an acid?
    Water acts as an acid by donating an H+ ion to form OH-.
  • How does water act as a base?
    Water acts as a base by accepting an H+ ion to form H3O+.
  • Which molecule or ion below is amphipathic?
    The question seems to be asking about amphoteric species, which are molecules or ions that can act as both acids and bases.
