Answer:

Water, amino acids, hydrogen carbonate ion (bicarbonate ion) and hydrogen sulfate ion (bisulfate ion) are common examples of amphiprotic species. Since they can donate a proton, all amphiprotic substances contain a hydrogen atom. Also, since they can act like an acid or a base, they are amphoteric.
