Chapter 11: Problem 15

State the normal \(\mathrm{pH}\) range of blood. What gas has an effect on blood pH? (p. 256)

Short Answer

Expert verified
Answer: The normal pH range of blood is 7.35 to 7.45, and carbon dioxide (CO2) is the primary gas that affects blood pH.

Step by step solution

01

Determine the normal pH range of blood

The normal pH range of blood is from 7.35 to 7.45, which means it is slightly alkaline. This is an essential range for the proper functioning of the body's cells and tissues.
02

Identify the gas that affects blood pH

Carbon dioxide (CO2) is the primary gas that has an effect on blood pH. When CO2 dissolves in blood, it forms carbonic acid (H2CO3), which can then dissociate into hydrogen ions (H+) and bicarbonate ions (HCO3-). An increase in CO2 levels in the blood leads to a decrease in pH (becoming more acidic), while a decrease in CO2 levels leads to an increase in pH (becoming more alkaline). This process helps in maintaining the acid-base balance in the blood.
