Concept explainers
a)
Interpretation: The conjugate acid and the conjugate base in the given reaction are to be identified.
Concept introduction: Conjugate acid and conjugate base are the substances that are formed by losing or gaining hydrogen ions. When an acid loses a hydrogen ion, then the product formed will be its conjugate base, and when a base accepts a hydrogen ion, the product formed will be its conjugate acid.
