List of amphoteric compounds
Without seeing reactions which show a compound as and acid and then a base, is there any way to tell an amphoteric compound just by looking at its Lewis structure? Is there a general way to tell? Also since the metalloids are generally amphoteric is there a list we should know?

Re: List of amphoteric compounds
I believe the book states that the best way to tell if a compound is amphoteric (having both qualities of an acid and a base), is to look at the atoms that compose it; the presence of a metalloid being an indicator that it is likely to be amphoteric. Otherwise, to be sure you would need to see how the compound acts in reactions.

Re: List of amphoteric compounds
I believe polyprotic acids, after giving off a hydrogen ion, can be amphoteric since it isn't as strong as originally and the reverse reaction is favored. Therefore it acts as slightly acidic while also slightly basic since the reverse reaction is possible, as well as the next forward reaction.
