Chapter 8, Problem 8.51AP

(a)

Interpretation Introduction

Interpretation:

The conjugate acid of ${\text{HS}}^{\text{-}}$ has to be drawn.

Concept Introduction:

Bronsted-Lowry Bases:  A Bronsted-Lowry base is a proton acceptor.  A base should contain a lone pair of electrons, which donates to form a new bond.  It can be neutral or can contain a negative charge.

Conjugate acid:  A conjugate acid is the product formed by a gain of a proton by a base.  The conjugate acid of the base B will be ${\text{HB}}^{\text{+}}\text{.}$

(b)

Interpretation Introduction

Interpretation:

The conjugate acid of ${\text{CO}}_{\text{3}}{}^{\text{2-}}$ has to be drawn.

Concept Introduction:

Refer to part (a).

(c)

Interpretation Introduction

Interpretation:

The conjugate acid of ${\text{NO}}_{\text{2}}{}^{\text{-}}$ has to be drawn.

Concept Introduction:

Refer to part (a).
