What is meant by the conjugate acid-base pair? Find the conjugate acid/base for the following species:
$HNO_{2}$,$CN^{-}$,$HClO_{4}$,$F^{-}$,$OH^{-}$,$CO_{3}^{2-}$,and $S^{2-}$
$HNO_{2}$,$CN^{-}$,$HClO_{4}$,$F^{-}$,$OH^{-}$,$CO_{3}^{2-}$,and $S^{2-}$
(N/A) conjugate acid-base pair is a pair of chemical species that differ by only one proton $(H^{+})$.
When an acid loses a proton,it forms its conjugate base.
When a base gains a proton,it forms its conjugate acid.
The conjugate acid-base pairs for the given species are listed in the table below:
When an acid loses a proton,it forms its conjugate base.
When a base gains a proton,it forms its conjugate acid.
The conjugate acid-base pairs for the given species are listed in the table below:
| Species | Conjugate Acid/Base |
| $HNO_{2}$ | $NO_{2}^{-}$ (Conjugate Base) |
| $CN^{-}$ | $HCN$ (Conjugate Acid) |
| $HClO_{4}$ | $ClO_{4}^{-}$ (Conjugate Base) |
| $F^{-}$ | $HF$ (Conjugate Acid) |
| $OH^{-}$ | $H_{2}O$ (Conjugate Acid) / $O^{2-}$ (Conjugate Base) |
| $CO_{3}^{2-}$ | $HCO_{3}^{-}$ (Conjugate Acid) |
| $S^{2-}$ | $HS^{-}$ (Conjugate Acid) |
