HSO4 can act as a base by gaining a hydrogen ion to make H2SO4. HSO4 can act as an acid by losing a hydrogen ion to make SO4.

What is an acid pair know as?

Acid base pairs differing ONE proton (H+) are called conjugate acid-base pair.Examples:H3O+ and H2OH2O and OH-NH4+ and NH3HBr and Br-HNO2 and NO2-H2SO4 and HSO4-HSO4- and SO42-HOCl and OCl-(In order of 'acid and base' respectively)

Why is HSO4 a weaker acid than H2SO4?

You can only get your answer in terms of the acid ionization constant, K_a. The K_a of H2SO4 is immeasurably high and the K_a of HSO4- is 1.3x10^-2. The higher the K_a, the stronger the acid. Therefore, H2SO4 is the stronger acid. Just a slight correction to the question, there is no HSO4. It exists as an ion HSO4-
