Hi!
In question #3 for the Achieve Week 10 homework we are asked to find the conjugate base and the conjugate acid of the same compound, HSO4-. This means that HSO4- can donate and receive H+, so it acts as both a Brønsted acid and a Brønsted base, and is therefore an amphoteric compound. Is this correct?
Thanks for any clarification!
Is HSO4- an amphoteric compound?

Yes! You explained it correctly yourself! Because it can both donate and accept protons, it demonstrates qualities of a Bronsted Lowry Acid and Base.

Yes exactly! amphoteric compounds can act as brosted acid and base because it is able to accept and donate H+. This means it can interact either as a base or an acid. :)

Re: Is HSO4- an amphoteric compound?
This is correct! HSO4- can either donate a proton (becoming SO42-) or accept a proton (becoming H2SO4). Another example of an amphoteric compound would be H2PO42-, which can either accept a proton to become H3PO4, or donate a proton to become HPO43-.
