Chapter 9, Problem 9.76AP

a.

Summary Introduction

To determine:

The formula of the conjugate acid formed from ${\text{HS}}^{-}$.

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 ${\text{H}}_2{\text{BO}}_3{}^{-}$.

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 acetate $\left({\text{CH}}_3{\text{COO}}^{-}\right)$.
