Options
- A. 6.0 to 6.4
- B. 7.36 to 7.42
- C. 6.4 to 6.95
- D. 7.8 to 8.0
Answer
B. 7.36 to 7.42
Step-by-step solution
The normal pH of human blood is slightly basic, typically maintained in a narrow range between 7.35 and 7.45. Among the given options, the range 7.36 to 7.42 correctly represents this physiological pH range. This pH is tightly regulated by various buffer systems in the body, primarily the bicarbonate buffer system. Answer: 7.36 to 7.42
