Chapter 15, Problem 15.126QE

(a)

Interpretation Introduction

Interpretation:

Whether the following reaction favors reactants products or neither has to be identified.

  $\text{HCl}\left(\text{aq}\right)+{\text{NH}}_3\left(\text{aq}\right)\rightleftharpoons {\text{NH}}_{\text{4}}\text{Cl}\left(\text{aq}\right)$

Concept Introduction:

An acid serves to accept an electron-pair from another electron-rich species while a base donates electrons to another electron-deficient species in the reaction in accordance with Lewis's definition. For instance of Lewis acids that have electron-deficient central atom ${\text{BF}}_3$ and ${\text{SO}}_3$.

(b)

Interpretation Introduction

Interpretation:

Whether the following reaction favors reactants products or neither has to be identified.

  ${\text{HNO}}_3\left(\text{aq}\right)+\text{NaOH}\left(\text{aq}\right)\rightleftharpoons {\text{NaNO}}_3\left(\text{aq}\right)+{\text{H}}_2\text{O}\left(\text{l}\right)$

Concept Introduction:

Refer to part (a).

(c)

Interpretation Introduction

Interpretation:

Whether the following reaction favors reactants products or neither has to be identified.

  $2\text{KCl}\left(\text{aq}\right)+\text{Ba}{\left(\text{OH}\right)}_2\left(\text{aq}\right)\rightleftharpoons {\text{BaCl}}_2+2\text{KOH}\left(\text{aq}\right)$

Concept Introduction:

Refer to part (a).

(d)

Interpretation Introduction

Interpretation:

Whether the following reaction favors reactants products or neither has to be identified.

  ${\text{NH}}_3\left(\text{aq}\right)+{\text{HSO}}_4^{-}\left(\text{aq}\right)\rightleftharpoons {\text{SO}}_4^{-}\left(\text{aq}\right)+{\text{NH}}_4^{+}\left(\text{aq}\right)$
