Chapter 25, Problem 25.35E

Interpretation Introduction

Interpretation:

The buffer system in the urine that keeps the urine $\text{pH}$ from dropping lower than $6$ is to be stated.

Concept introduction:

Kidneys can excrete varying amounts of acid and base. Like the lungs, kidneys play important role in $\text{pH}$ control. For acidic blood, the excretion of the hydrogen ions by the kidneys decreases the urine $\text{pH}$ and increases the blood $\text{pH}$ back to normal.
