Quick Identification
Hey does anyone have any tips on how to quickly identify an amphoteric compound without having to memorize them from a chart?

Hi!
I would say you don't have to memorise them, but a general idea works. Amphoteric oxides are usually transition metals (d-block elements) or metalloids (between the metals and non-metals).
An amphoteric oxide can neutralise both acid and a bases. So to identify if a compound is amphoteric, you can examine its reaction with an acid and reaction with a base as well.
I hope this helped.

Re: Quick Identification
If theres an H that means it can act as an acid and give it up and if there's a negative charge it can also take a proton to act as a base so if there's both, like Juliana said, you can usually assume its amphoteric. I think those would also be amphiprotic because they are donating/receiving a proton.
