(a)
Interpretation:
The Bronsted acids and bases in both reactants and products of the given proton transfer equilibrium has to be identified.
Concept Introduction:
Bronsted-Lowry acid is a proton donor as well Bronsted-Lowry base is a proton acceptor.
Conjugate acid of a base has one more proton than its base. Simply add a proton to the base to get its conjugate acid.
Conjugate base of an acid has one less proton than its acid. Simply remove a proton from the acid to get its conjugate base.
(b)
Interpretation:
The Lewis acid and base in the given proton transfer equilibrium has to be identified.
Concept Introduction:
There is simple way to identify whether the given species is Lewis acid or Lewis base. A species which accepts electron pair is called Lewis acid and a species which donates electron pair is called Lewis base.
