To examine: Whether the statement, “A 10 -8 M solution of HCl has a pH of 8”, is true or false. Introduction: The potential of hydrogen (pH) is the negative logarithm of the concentration of hydrogen (H + ) ions. It determines acidity and alkalinity of a substance. Acids have pH lower than 7, whereas alkalis have pH more than 7. The solutions that are not considered under acid or alkali are called neutral solutions and have a pH equal to 7.

Question

Chapter 2, Problem 1P

Summary Introduction

To examine: Whether the statement, “A 10^-8 M solution of HCl has a pH of 8”, is true or false.

Introduction: The potential of hydrogen (pH) is the negative logarithm of the concentration of hydrogen (H⁺ ) ions. It determines acidity and alkalinity of a substance. Acids have pH lower than 7, whereas alkalis have pH more than 7. The solutions that are not considered under acid or alkali are called neutral solutions and have a pH equal to 7.

Expert Solution & Answer

Answer to Problem 1P

Correct answer: The statement is false.

Explanation of Solution

The pH of hydrochloric acid (HCL) cannot be equal to 8 because HCL is a strong acid, and the pH of an acidic solution can never be higher than 7.

Hence, the statement is false.
