Physiologic pH is maintained at approximately 7.4 because bicarbonate (HCO₃)and carbonic acid (H₂CO₃)exist in a ratio of:
A) 20:1
B) 1:20
C) 10:2
D) 10:5

Quizplus · Accepted Answer

The relationship between HCO₃ and H₂CO₃ is usually expressed as a ratio.When the pH is 7.4,this ratio is 20:1 (HCO₃:H₂CO₃).The other options do not accurately identify physiologic pH by the correct ratio of HCO₃ and H₂CO₃.
