Consider the pH of the following body fluids:
| Body Fluid | pH |
| Stomach acid | 1.4 |
| Pancreatic juice | 8.4 |
| Sweat | 4.8 |
| Urine | 5.3 |
| Cerebrospinal fluid | 7.3 |
a. Place the pH values of the body fluids on the list in order of most acidic to most basic.
b. Which body fluid has the highest [H_{3}O^{+}]?
a. The most acidic body fluid is the one with the lowest pH, and the most basic is the body fluid with the highest pH: stomach acid ( 1.4), sweat (4.8), urine (5.3), cerebrospinal fluid (7.3), pancreatic juice (8.4).
b. The body fluid with the highest [H_{3}O^{+}] would have the lowest pH value, which is stomach acid.
