Chapter 9, Problem 9.75AP

a.

Summary Introduction

To determine:

The formula of the conjugate acid formed from lactate $\left({\text{CH}}_3\text{CH}\left(\text{OH}\right){\text{COO}}^{-}\right)$.

Introduction:

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

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

$\text{Base}\stackrel{+{\text{H}}^{+}}{\to }\text{Conjugate}\text{acid}$

b.

Summary Introduction

To determine:

The formula of the conjugate acid formed from aminomethane $\left({\text{CH}}_3{\text{NH}}_2\right)$.

Introduction:

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

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

$\text{Base}\stackrel{+{\text{H}}^{+}}{\to }\text{Conjugate}\text{acid}$

c.

Summary Introduction

To determine:

The formula of the conjugate acid formed from phosphate $\left({\text{PO}}_4{}^{3-}\right)$.

Introduction:
