Chapter 8.1, Problem 8.2PP

(a)

Interpretation Introduction

Interpretation:

The conjugate base of given acids has to be written.  Also, the stronger acid has to be identified for each pair.

  ${\text{H}}_{\text{2}}\text{O}\text{or}{\text{HN}}_{\text{4}}^{\text{+}}{\text{H}}_{\text{2}}{\text{SO}}_{\text{4}}\text{or}{\text{H}}_{\text{2}}{\text{SO}}_{\text{3}}$

Concept Introduction:

Acids and bases classified as strong when the reaction with water undergoes 100% completion and as weak when the reaction with water is much less than 100% complete.  The relative strength of Acid-base are given by

Figure 1

Interpretation Introduction

Interpretation:

The conjugate acid of given bases has to be written.  Also, the stronger base has to be identified.

  ${\text{CO}}_{\text{3}}^{\text{2-}}\text{or}{\text{PO}}_{\text{4}}^{\text{3-}}{\text{HCO}}_{\text{3}}^{\text{-}}\text{or}{\text{HPO}}_{\text{4}}^{\text{2-}}$
