Chapter 11.6, Problem 11.43QAP
Interpretation Introduction

Interpretation: “The neutral solution has a pHof7”should be explained

Concept Introduction:

pH of a solution is defined as the negative logarithm of the hydrogen ion concentration of the aqueous solution.

Thus, pH=log[H+]

► Water is a very weak conductor of electricity. This suggests that it undergoes self-ionization to a very small extent. Due to self ionization, the following equilibrium is set up between water and its ions.

H2O(l)+H2O(l)H+(aq)+OH(aq)

Applying law of mass action, the equilibrium constant Kc for the self ionization of water can be written as

Kc=[H+][OH][H2O]2Kc[H2O]2=[H+][OH]

Since degree of ionization of water is very low, its ionization does not appreciably changes the concentration of water molecules. Therefore [H2O]2 may be regarded as constant.

KcK=[H+][OH]

where K is a constant representing [H2O]2

Now,

Kw=[H+][OH]

Where Kw is the product of two constant KcandK

Kw is called the ionic product of water and its value is 1×1014
