Knowing Amphoteric Compunds

[Tracy Tran 3L]

How would I be able to identify an amphoteric compound or is this something I just need to memorize rather than figure out?

To figure out whether a compound is amphoteric or not, just see if the compound can both donate a proton or accept a proton. For example, in the compound HSO4-, it can both donate a proton and accept a proton.

You should look if the compound can accept and receive a proton which gives allows it to have properties of both a acid and base.

Amphoteric compounds can be identified by reacting with a strong acid and reacting with a strong base. If the equation/reaction shows that the compound can act as both an acid and base (which is true when the reaction neutralizes the strong acid/base), we know that it is amphoteric.

A compound is amphoteric if it can act as both an acid or base, meaning it can either lose a H+ proton or gain one. For example HSO3- is amphoteric.

The way I recognize amphoteric compounds is making sure the compound/molecule has both a H (to donate in the case it acts as an acid) AND a negative charge (to donate electrons in the case it acts as a base). I'm not sure if this is 100% accurate it's just the way I do it - feel free to correct me if I'm wrong.
