Chapter 14, Problem 14.33CP

For each of the following reactions, identify the Brønsted–Lowry acids and bases:

Interpretation Introduction

Interpretation:

For given reactions, Bronsted-Lowry acids and bases has to be identified.

Concept introduction:

Bronsted-Lowry acid and bases:

The chemical species which is able to donate hydrogen ion to other substance known as Bronsted-Lowry acid and the species which is able to accept hydrogen ion from another species known as Bronsted-Lowry base.

Answer to Problem 14.33CP

In first reaction,

${\text{HCO}}_3{}^{-}$ is Bronsted-Lowry acid and ${\text{H}}_{\text{3}}{\text{O}}^{\text{+}}$ is Bronsted-Lowry base.

In second reaction,

${\text{HCO}}_3^{+}$ is Bronsted-Lowry base and ${\text{F}}^{\text{\_}}$ is Bronsted-Lowry acid.

Explanation of Solution

Given

Figure 1

In first reaction:

The chemical species which is able to donate hydrogen ion to other substance known as Bronsted-Lowry acid.  In first reaction ${\text{HCO}}_3{}^{-}$ donates hydrogen ion, hence it is Bronsted-Lowry acid.

The species which is able to accept hydrogen ion from another species known as Bronsted-Lowry base.  In this reaction, ${\text{H}}_{\text{2}}\text{O}$ accepts proton from ${\text{HCO}}_3{}^{-}$, hence ${\text{H}}_{\text{2}}\text{O}$ is Bronsted-Lowry base.

In second reaction:

The chemical species which is able to donate hydrogen ion to other substance known as Bronsted-Lowry acid.  In first reaction $\text{HF}$ donates hydrogen ion, hence it is Bronsted-Lowry acid.

The species which is able to accept hydrogen ion from another species known as Bronsted-Lowry base.  In this reaction, ${\text{HCO}}_3{}^{-}$ accepts proton from $\text{HF}$, hence ${\text{HCO}}_3{}^{-}$ is Bronsted-Lowry base.
