question_answer 1)

The species \[{{H}_{2}}O,HCO_{3}^{-},HSO_{4}^{-},N{{H}_{3}}\] can act both as Bronsted acids and bases. For each case give the corresponding conjugate acid and base.

Answer:

Species Conjugate base Conjugate acid \[{{H}_{2}}O\] \[O{{H}^{-}}\] \[H_{3}^{+}O\] \[HCO_{3}^{-}\] \[CO_{3}^{2-}\] \[{{H}_{2}}C{{O}_{3}}\] \[HSO_{4}^{-}\] \[SO_{4}^{2-}\] \[{{H}_{2}}S{{O}_{4}}\] \[N{{H}_{3}}\] \[NH_{2}^{-}\] \[NH_{4}^{+}\]
