Amphoteric compounds

What are amphoteric compounds and why are they important? Would h20 be considered an amphoteric compound?

Essentially, amphoteric compounds can act as both an acid or a base. Water is a classic amphoteric compound as it can donate one of its H+ to become OH- or accept H+ to become H3O+.

An amphoteric compound is a compound that can act as both an acid and a base which means it can both accept and donate a proton. Yes, water is an amphoteric compound.

Amphoteric compounds can have both acidic and basic character. (e.g. H2O can become H3O+ or OH-)

Dr. Lavelle pointed out in class the diagonal band of amphoteric oxides (Be, Al, Ga, Sn, Sb, Pb), quite similar to the band of metalloids. All of these oxides (e.g. Al2O3) are amphoteric.
