Amphiprotic species. |
|
An amphiprotic substance is one that can either donate a proton (act as an acid) or accept a proton (act as a base) Below are some examples of amphiprotic substances. |
|
HCO3- can act as an acid (donating a proton), as shown on the right. | |
Or HCO3- can act as a base (accepting a proton) | |
HSO4- can act as an acid (donating a proton), as shown on the right | |
Or HSO4- can act as a base (accepting a proton) | |
H2O can act as an acid (donating a proton) | |
Or H2O can act as a base (accepting a proton) | |
