Chapter 18, Problem 18.159P

(a)

Interpretation Introduction

Interpretation:

Liquid ammonia autoionizes like water:

  2NH3(l)NH4+(am)+NH2-(am)

The ion-product constant expression, Kam has to be written (am represents solvation by NH3).

Concept Introduction:

Equilibrium constant:

The relationship between the concentration of products and concentration of reactants in a chemical reaction at equilibrium is said to be equilibrium constant.  It is denoted by K.

For a reaction,

  xX + yY  zZ

The expression of K can be given as

  Kc = [Z]z[X]x[Y]ywhere, [X] = equilibrium concentration of X [Y] = equilibrium concentration of Y [Z] = equilibrium concentration of Z

(b)

Interpretation Introduction

Interpretation:

The strongest acid and base that can exist in NH3(l) has to be given.

(c)

Interpretation Introduction

Interpretation:

HNO3andHCOOH are levelled in NH3(l).  It has to be explained with equations.

(d)

Interpretation Introduction

Interpretation:

At the boiling point of ammonia (-33°C), Kam=5.1×10-27, the [NH4+] has to be calculated at this temperature.

Concept Introduction:

Equilibrium constant:

The relationship between the concentration of products and concentration of reactants in a chemical reaction at equilibrium is said to be equilibrium constant.  It is denoted by K.

For a reaction,

  xX + yY  zZ

The expression of K can be given as

  Kc = [Z]z[X]x[Y]ywhere, [X] = equilibrium concentration of X [Y] = equilibrium concentration of Y [Z] = equilibrium concentration of Z

(e)

Interpretation Introduction

Interpretation:

Pure sulfuric acid also autoionizes.  The ion-product constant expression, Ksulf has to be written and the concentration of the conjugate base at 20°C has to be calculated.  (Ksulf = 2.7×10-4at20°C)
