Chapter 16.2, Problem 3RQ

(a)

Interpretation Introduction

Interpretation:The concentration of H+ of the solution if pH is 4.32 needs to be determined.

Concept introduction: pH isa measure of the acidity or alkalinity of a solution. The pH scale generally varies from 0 to 14.

The equation for pH is given by,

  pH=-log[H+] where, [H+]is concentration of hydrogen ion.

Answer to Problem 3RQ

The concentration of H+ is 4.79×105 M

Explanation of Solution

Here the pH of the solution is 4.32.

  4.32=-log[H+][H+]=10-4.32=4.79×10-5

(b)

Interpretation Introduction

Interpretation: The concentration of H+ of the solution if pH is 11.15 needs to be determined.

Concept introduction: pH is a measure of the acidity or alkalinity of a solution. The pH scale generally varies from 0 to 14.

The equation for pH is given by,

  pH=-log[H+] where, [H+]is concentration of hydrogen ion.

(b)

Expert Solution

Answer to Problem 3RQ

The concentration of H+ is 7.08×1012 .

Explanation of Solution

Here the pH of the solution is 11.15

  11.15=-log[H+][H+]=10-11.15=7.08×10-12
