Answer:
HSO4-
Explanation:
The conjugate acid is just adding a H+ ion to your base.
so since here it is [tex]SO_4 ^{-2} + H^{+} = HSO_4 ^{-}[/tex]
So remember that when adding a H+ to a molecule,
you add
-an H to the formula
if lets say the formula was NH3 (ammonia), then adding H+ would
make it NH4+, since initially it wasn't a polyatomic ion, and you add
H+, the sign would become +.
if the formula didn't have H in the beginning, you add it in the beginning of the formula. And if the ion did was just -, such as
CN-, then H+ would be HCN, you add the H and do -sign + 1, here it is 0.
Conjugate base follows the same concept, but you remove the H+ ion, so H2SO3 would be H2SO3 - H = HSO3-.
Hope that helps
