Chapter 9, Problem 9.43E

The $\text{pH}$ values listed in Table 9.1 are generally the average values for the listed materials. Most natural materials, such as body fluids and fruit juices, have $\text{pH}$ values that cover a range for different samples. Some measured $\text{pH}$ values for specific body fluid samples are given below. Convert each one to $\left[{\text{H}}^{+}\right]$, and classify the fluid as acidic, basic, or neutral.

a. Blood, $\text{pH}=\text{7}\text{.41}$

b. Gastric juice, $\text{pH}=\text{1}\text{.60}$

c. Urine, $\text{pH}=\text{5}\text{.93}$

d. Saliva, $\text{pH}=\text{6}\text{.85}$

e. Pancreatic juice, $\text{pH}=\text{7}\text{.85}$
