Given the following information,what is the pH?
Ratio of [HCO₃]/[CO₂] = 20/0.5
PK = 6.1
Log of 10 = 1.0
Log of 20 = 1.3
Log of 40 = 1.6
A) pH = 7.0
B) pH = 7.4
C) = 7.7
D) It is impossible to determine the pH with the information provided.

Using the Henderson-Hasselbalch equation:

pH = PK + log([HCO₃]/[CO₂])

First, we need to find the ratio of [HCO₃]/[CO₂]:
[HCO₃]/[CO₂] = 20/0.5 = 40

Substituting in the values:

pH = 6.1 + log(40)
pH = 6.1 + 1.6
pH = 7.7

Therefore, the answer is C, pH = 7.7.
