18Acid Base Properties ReactionsMedium1 mark

Sulfuric acid dissociates in water in two stages. The equations for each stage are shown.

H_{2} S O_{4} ⇌ H^{+} + HS O_{4}^{-}

HS O_{4}^{-} ⇌ H^{+} + S O_{4}^{2 -}

Which statements about these equations are correct?

1
HSO $_{4}^{-}$ can donate and accept protons.
2
H $_{2}$ SO $_{4}$ is a proton donor.
3
SO $_{4}^{2 -}$ is the only base.
