Chapter 22, Problem 148AE

In glycine, the carboxylic acid group has Ka = 4.3 × 10−3 and the amino group has Kb = 6.0 × 10−5. Use these equilibrium constant values to calculate the equilibrium constants for the following.

a. H + 3 NCH 2 CO 2 +H 2 O H 2 NCH 2 CO 2 +H 3 O +

b. H 2 NCH 2 CO 2 +H 2 O H 2 NCH 2 CO 2 H+OH

c. H + 3 NCH 2 CO 2 H 2 H + +H 2 NCH 2 CO 2

Interpretation Introduction

Interpretation: The equilibrium constants for the following reactions are to be calculated.

Concept introduction: Equilibrium constant is defined as the ratio of the concentration of the products to the concentration of the reactants present at equilibrium in a reversible reaction at a given temperature. It is denoted by K and is a dimensionless quantity. Its value decide the direction of the chemical reaction, if the value of K is less than one the reaction will proceed towards left but when its value is greater than one the reaction will proceed in the right direction.

To determine: The equilibrium constant for the reaction.

Answer to Problem 148AE

Answer

The equilibrium constant for the reaction is, Ka= 1.6×10-10_ .

Explanation of Solution

Explanation

The equilibrium constant for the reaction is 1.6×10-10_ .

The given reaction is,

+H3NCH2CO2 + H2 H2NCH2CO2 + H3O+

In the given reaction, dissociation of an acid occurs.

The equilibrium constant expression for the above reaction is,

Ka=[H2NCH2CO2][H3O+][+H3NCH2COO]

Where,

  • Ka is the acid dissociation constant.

Given

Basicity of amino group(Kb)= 6.0×105

The given reaction occurs in an aqueous medium. In an aqueous solution, the acidity and basicity of an acid and its conjugate base is related by the expression,

Ka × Kb = 1014

Substitute the value of Kb in the above expression.

Ka=10Kb14=10146.0×1010=1.6×1010

Hence, the equilibrium constant for the reaction is 1.6×10-10_ .

Answer to Problem 148AE

Answer

The equilibrium constant for the reaction is, Kb= 2.32×10-12_ .

Explanation of Solution

Explanation

The equilibrium constant for the reaction is 2.32×10-12_ .

The given reaction is,

H2NCH2CO2+H2 H2NCH2COOH+OH

In the given reaction dissociation of a base occurs. The equilibrium constant expression for the above reaction is,

Kb=[H2NCH2COOH][OH][H2NCH2COO]

Where,

  • Kb is the base ionization constant.

Kaof carboxylic acid= 4.3×103

The given reaction occurs in an aqueous medium. In an aqueous solution, the acidity and basicity of an acid and its conjugate base is related by the expression,

Ka × Kb = 1014

Substitute the value of Ka in the above expression.

Kb=10Ka14=10144.3×103=2.32×1012

Hence, the equilibrium constant for the reaction is 2.32×10-12_ .

The equilibrium constant for the reaction is, Ka=1.6×10-10_ .

Explanation of Solution

Explanation

The equilibrium constant for the reaction is 1.6×10-10_ .

The given reaction is,

+H3NCH2COOH   2H++ H2NCH2COO- 

In the given reaction dissociation of an acid occurs. Therefore, the equilibrium constant expression for the above reaction is,

Ka=[H2NCH2CO2][2H+][+H3NCH2COOH]

Where,

  • Ka is the acid dissociation constant.

Basicity of amino group(Kb) = 6.0×105

The given reaction occurs in an aqueous medium. In an aqueous solution, the acidity and basicity of an acid and its conjugate base is related by the expression,

Ka × Kb = 1014

Substitute the value of Kb in the above expression.

Ka=10Kb14=10146.0×1010=1.6×1010
