How do you identify an amphoteric compound? Should we go off the list BeO, Al2O3, Ga2, O3, SnO2, SbO5, PbO2, but none of the answers correspond?

Amphoteric compound means that it can act as both an acid and base. In other words, it can donate or accept protons. molecules such as HSO4- can accept a proton or donate one depending on how acidic or basic the environment is. In this problem, only H2PO4- has this ability. bc it can accept a proton for a neutral charge or lose one

Hi!

When identifying an Amphoteric compound, you must look for a molecule that has the ability to remove and add hydrogen ions from other molecules. Usually, they will have multiple hydrogen atoms or both basic and acidic components. The answer is H2PO4- as this is the only molecule that can both donate H+ and accept H+
