Explanation:
According to the Bronsted-Lowry conjugate acid-base theory:
1. An acid is a substance which looses donates protons and thus forming conjugate base.
[tex]HA(aq)\rightarrow H^+(aq)+A^-(aq)(\text{conjugate base})[/tex]
2. A base is a substance which accepts protons and thus forming conjugate acid.
[tex]BOH(aq)+H^+(aq)\rightarrow BOH_2^{+}(aq)(\text{conjugate acid})[/tex]
For example:
[tex]HNO_3(aq)+NH_3(aq)\rightarrow NO_3^{-}(aq)+NH_4^{+}(aq)[/tex]
Here, [tex]HNO_3[/tex] is loosing a proton, thus it is considered as an acid and after losing a proton, it forms [tex]NO_3^{-}[/tex] which is a conjugate base.
And, [tex]NH_3[/tex] is gaining a proton, thus it is considered as a base and after gaining a proton, it forms [tex]NH_4^{+}[/tex] which is a conjugate acid.
