Chapter 9, Problem 9.73AP

a.

Summary Introduction

To determine:

The formula of the conjugate base formed from nitrous acid $\left({\text{HNO}}_2\right)$.

Introduction:

Any substance that has the tendency to donate a proton $\left({\text{H}}^{+}\right)$ to other substance (base) is called an acid. The substance/species that formed after the donation of a proton by an acid is called its conjugate base.

The general reaction that shows the formation of conjugate base is as follows.

$\text{Acid}\to \text{Conjugate}\text{base}+{\text{H}}^{+}$

b.

Summary Introduction

To determine:

The formula of the conjugate base formed from methylammonium $\left({\text{CH}}_3{\text{NH}}_3{}^{+}\right)$.

Introduction:

Any substance that has the tendency to donate a proton $\left({\text{H}}^{+}\right)$ to other substance (base) is called an acid. The substance/species that formed after the donation of a proton by an acid is called its conjugate base.

The general reaction that shows the formation of conjugate base is as follows.

$\text{Acid}\to \text{Conjugate}\text{base}+{\text{H}}^{+}$

c.

Summary Introduction

To determine:

The formula of the conjugate base formed from formic acid $\left(\text{HCOOH}\right)$.

Introduction:

Any substance that has the tendency to donate a proton $\left({\text{H}}^{+}\right)$ to other substance (base) is called an acid. The substance/species that formed after the donation of a proton by an acid is called its conjugate base.

The general reaction that shows the formation of conjugate base is as follows.

$\text{Acid}\to \text{Conjugate}\text{base}+{\text{H}}^{+}$
