Question

HSO4- + BrO- <--> ____ (ACID) + ____ (BASE)

Answer 1

Students often make this type problem so much harder than it is. The acid is the one with more H ions; the base is the one with fewer H ions.
HSO4^- + BrO^- ==> HBrO + SO4^2-
So the pairs are HSO4^- and SO4^2-
with the other pair BrO^- and HBrO.
For the pair then the HSO4^- must be the acid because it contains more H than SO4^2-. Of course the SO4^2- must be the base since it contains no H at all.

Answer 2

no
