What is meant by the conjugate acid-base pair? Find the conjugate acid/base for the following species: \[HN{{O}_{3}},\overset{-}{\mathop{C}}\,N,HCl{{O}_{4}},{{F}^{-}},O{{H}^{-}},CO_{3}^{2-},{{S}^{2-}}\]

Answer:

  Species Conjugate acid Conjugate base \[O{{H}^{-}}\] \[{{H}_{2}}O\] \[{{O}^{2-}}\] \[CO_{3}^{2-}\] \[HCO_{3}^{-}\] \[-\] \[{{S}^{2-}}\] \[H{{S}^{-}}\] \[-\] \[HN{{O}_{3}}\] \[{{H}_{2}}NO_{3}^{+}\] \[NO_{3}^{-}\] \[\bar{C}N\] \[HCN\] \[-\] \[HCI{{O}_{4}}\] \[-\] \[CIO_{4}^{-}\] \[{{F}^{-}}\] \[HF\] \[-\].
