Chapter 5, Problem 5.18P
Interpretation Introduction

Interpretation:

The equilibrium constant expression for given reaction has to be estimated and also the extent of dissociation is small and α is inversely proportional to the square root of the total pressure, αp-1/2 has to be showed.

Concept Introduction:

Ionic-product constant for water: It is the hydronium ion concentration times the OH concentration present in the solution.

H2O(l)+H2O(l)H3O+(aq)+OH(aq)K=[ H3O+ ][ OH ][ H2O ][ H2O ][ H3O+ ]=[ OH ]=1.00×107MKW=K[ H2O ][ H2O ]=[ H3O+ ][ OH ]KW=1.00×1014M

The Kw will apply to all aqueous solution.

For acidic solution [H3O+] is large that is [H3O+]>107Mand[OH]<107M

For basic solution [OH] is large that is [H3O+]<107Mand[OH]>107M

pH: The concentration of hydrogen ion is measured using pH scale.  The pH of a solution is a figure that expresses the acidity or the alkalinity of a given solution.

It is defined as the negative base-10 logarithm of the hydrogen or hydronium ion concentration.

pH=-log[H3O+]
