The products of an acid-base reaction are H3O+ & SO4-2. Write the balanced equation for the reaction and identify the conjugate acid-base pairs.
HSO4-(aq) + H2O(L) <---> H3O+(aq) + SO4-2(aq)
Acid- HSO4- Base - H2O CA - H3O+ CB - SO4-2
H3O+(aq) + SO4-2(aq) <---> HSO4-(aq) +H2O(L)
Acid- H3O+ Base - SO4-2 CA -HSO4- CB - H2O
HSO4-(aq) + H2O(L) <---> H3O+(aq) + SO4-2(aq)
Acid- HSO4- Base - H2O CA - SO4-2 CB - H3O+
