Concept explainers
(a)
Interpretation:
Each of the species in the given equation has to be labeled as acid, base, conjugate acid or conjugate base.
Concept Information:
When a Bronsted acid donates a proton, what remains of the acid is known as a conjugate base; when a Bronsted base accepts a proton, the newly formed protonated species is known as a conjugate acid. This can be given by the below equation as shown in Figure 1.
Figure 1
The reactant that loses a proton is the acid and the reactant that gains a proton is the base.
Each product is the conjugate of one of the reactant.
Two species that differ only by a proton constitute a conjugate pair
Addition of proton to a species gives its conjugate acid whereas removal of proton from a species gives its conjugate base.
