Question

Be sure to answer all parts.

The hydronium ion concentration in blood of three different patients was:

Patient [H30+]

A 3.15 x 10 ^{- 8}

B 1.26 x 10 ^{- 8}

C 3.97 x 10 ^{- 8}

What is the pH of each patient's blood? If the normal range is 7.30 − 7.50, which, if any, of these patients has an abnormal blood pH?

Patient A: pH =

Inside normal range?

Patient B: pH =

Inside normal range?

Patient C: pH =

Inside normal range?

 

Answer 1

Patient A: pH = (-) log [H+] = 7.50, yes pH is inside the normal range

Patient B: pH = 7.90, pH is outside of the normal range

Patient C: pH = 7.40, yes pH is inside the normal range
