  • question_answer Write down the conjugate acid and conjugate base of (i) \[{{H}_{2}}O\]                              (ii) \[HSO_{4}^{-}\] (iii) \[N{{H}_{3}}\]                            (iv) \[H{{S}^{-}}\]

    Answer:

                    (i) \[{{H}_{3}}{{O}^{+}},\,O{{H}^{-}}\]                     (ii) \[{{H}_{2}}S{{O}_{4}},\,SO_{4}^{2-}\]                 (iii) \[NH_{4}^{+},\,NH_{2}^{-}\]                                     (iv) \[{{H}_{2}}S,\,{{S}^{2-}}\] Note. To write the conjugate acid of the given species, add \[{{H}^{+}}\] ion. To write the conjugate base of the given species, subtract \[{{H}^{+}}\] ion.
