How do you identify an amphoteric compound?

If the compound can act as both an acid and a base, the compound is amphoteric. The most common example is H2O. It can gain a proton to become a hydronium ion (H3O+) or lose a proton to become a hydroxide ion (OH-).

I'm not too sure if we will need to know much more besides water in terms of the amphoteric compounds

Yeah, Lavelle hasn't really gone over amphoteric compounds in lecture yet, so I think it would be best to just know that H2O is the standard amphoteric compound because it has the same concentration of H+ and OH- ions.

The one amphoteric compound we have gone over in lecture is H2O since it can act as a base and acid. I think it is sufficient enough to know that H2O is the main amphoteric compound.
