Chapter 17, Problem 69E
Interpretation Introduction

Interpretation:

The reason for preferring pH scale by chemists to express hydrogen ion concentration is to be stated. Advantage of saying pH=4 rather than [H+]=104M is to be stated.

Concept introduction:

Concentration of a species can be expressed in different ways. pH is use to express hydrogen ion concentration in a solution. Logarithm of base 10 is written as p. Value of pX is written as log10X

[References] Use the References to access important values if needed for this question. The pH scale was designed to make it convenient to express hydrogen ion concentrations that are small in aqueous solutions. The definiton of pH is in terms of base 10 logarithms. pH = – log[H*] where |H†| is the hydrogen ion concentration. a. If the hydrogen ion concentration in a solution is 7.68 × 10-³ mol/L, the pH is b. If the pH of a solution is 3.140, the hydrogen ion concentration is mol/L.
