Chapter 14, Problem 55E

Interpretation Introduction

(a)

Interpretation:

The molar hydrogen ion concentration of saliva with $\text{pH}=\text{6}\text{.55}$ is to be calculated.

Concept introduction:

The $\text{pH}$ scale tells about the strength of an acid and a base. It measures the concentration of the hydrogen ions. There is an inverse relationship between the $\text{pH}$ value and the concentration of the hydrogen ion. Higher the concentration of hydrogen ions, lesser the value of $\text{pH}$. There is an inverse relationship between the $\text{pOH}$ value and the concentration of the hydroxide ion. Higher the concentration of hydroxide ions, lesser the value of $\text{pOH}$.

Interpretation Introduction

(b)

Interpretation:

The molar hydrogen ion concentration of blood with $\text{pH}=\text{7}\text{.50}$ is to be calculated.

Concept introduction:

The $\text{pH}$ scale tells about the strength of an acid and a base. It measures the concentration of the hydrogen ions. There is an inverse relationship between the $\text{pH}$ value and the concentration of the hydrogen ion. Higher the concentration of hydrogen ions is lesser the value of $\text{pH}$. There is an inverse relationship between the $\text{pOH}$ value and the concentration of the hydroxide ion. Higher the concentration of hydroxide ions, lesser the value of $\text{pOH}$.
