So besides water, they get kind of weird.
Hydrogen carbonate, bisulfate, amino acids, BUT MOST IMPORTANTLY (and probably the only one you will need to know) WATER

Water will most likely be the only one we need to know, otherwise, it will be specified if a compound is amphoteric.

Can you explain why amino acids would be amphoteric?

Aluminium Oxide (Al2O3) is another amphoteric compound. It is able to have reactions where it acts as an acid or base, depending on the other species it is reacting with.

An amphoteric compound may be able to add an H+ or remove an H+. Compounds like this include HSO4- and H2PO4-.
