WebIn water, anyway, HBr is fully dissociated and it shouldn't be “reformed” like that. The proton will return to be solvated in the solution. I did looked up for pKa values and compared. According to the pKa values that I've seen, HBr was 1000 times stronger acid than protonated acetone. That's why the question. http://commonorganicchemistry.com/Common_Reagents/Sodium_Bisulfite/Sodium_Bisulfite.htm
