An substance is described as amphiprotic if it can both donate or accept a proton.
The best example is bicarbonate:
HCO3- + H+ --> H2CO3
or
HCO3- --> CO3-2 + H+

a) Amphiprotic just means that the molecule can either accept or donate a proton (H+). In this case, HCO3- is amphiprotic because it can accept a proton (or hydrogen) to become H2CO3 or donate a proton to become (CO3)2-. Because its reacting with HI, a strong acid, HCO3- will act as a base, or proton acceptor. b) HCO3- + HI ---> H2CO3 + I-

Your formula is incomplete. It lacks the charge of the ion. The equation is HCO3- + HI --> H2CO3 + I- The amphiprotic substance is the bicarbonate ion. It can either donate its proton (and turn to a carbonate ion) or accept a proton (and becomes carbonic acid). Because HI is a strong acid, the bicarbonate ion will accept the proton, so is the "proton acceptor" or the Bronsted-Lowry Base.

water is probably the best known amphiprotic substance (easily donating or receiving a proton) - all amphiprotic substances contain hydrogen which has unique bonding properties
