2. (7) a) Calculate the pH of normal arterial blood using the information given below:

pK

Solution

If you double CO2, then you double H+

Let\'s call the original number x

pH = -log(x)

New pH = -log(2x)

New pH = -log2 - logx

The logarithm of 2 is less than 1. Therefore, we must pick the only number that has a difference of less than 1 and is smaller than the original pH (more acidic)
